332 |
| 10118 | 333 ** The `lookup' function was extended to be more useful for |
| 334 general-purpose binary searching. Using this improvement, the | |
| 335 ismember function was rewritten for significantly better | |
| 336 performance. | |
| 9352 | 337 |
| 338 ** Real, integer and logical matrices, when used in indexing, will now | |
| 339 cache the internal index_vector value (zero-based indices) when | |
| 340 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 341 subsequent indexing by the same matrix. In particular, this means it |
| 342 is no longer needed to avoid repeated indexing by logical arrays | |
| 343 using find for performance reasons. | |
| 9888 | 344 |
| 10118 | 345 ** Logical matrices are now treated more efficiently when used as |
| 346 indices. Octave will keep the index as a logical mask unless the | |
| 347 ratio of true elements is small enough, using a specialized | |
| 348 code. Previously, all logical matrices were always first converted | |
| 349 to index vectors. This results in savings in both memory and | |
| 350 computing time. | |
| 9480 | 351 |
| 10118 | 352 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 353 functions for better performance. These functions are now faster, | |
| 354 can deliver more economized results for ranges, and can reuse the | |
| 355 index cache mechanism described in previous paragraph. | |
| 356 | |
| 357 ** The built-in function equivalents to associative operators (`plus', | |
| 358 `times', `mtimes', `and', and `or') have been extended to accept | |
| 359 multiple arguments. This is especially useful for summing | |
| 360 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 361 |
| 9449 | 362 matrix_sum = plus (matrix_list{:}); |
| 363 | |
| 10118 | 364 ** An FTP object type based on libcurl has been implemented. These |
| 365 objects allow ftp connections, downloads and uploads to be | |
| 366 managed. For example, | |
| 9880 | 367 |
| 10118 | 368 fp = ftp ("ftp.octave.org); |
| 369 cd (fp, "gnu/octave"); | |
| 370 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 371 close (fp); | |
| 9880 | 372 |
| 10118 | 373 ** The default behavior of `assert (observed, expected)' has been |
| 374 relaxed to employ less strict checking that does not require the | |
| 375 internals of the values to match. This avoids previously valid | |
| 376 tests from breaking due to new internal classes introduced in future | |
| 377 Octave versions. | |
| 9449 | 378 |
| 379 For instance, all of these assertions were true in Octave 3.0.x | |
| 380 but false in 3.2.x due to new optimizations and improvements: | |
| 381 | |
| 382 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 383 assert (zeros (0, 0), []) | |
| 384 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 385 |
| 10118 | 386 ** The behavior of library functions `ismatrix', `issquare', and |
| 387 `issymmetric' has been changed for better consistency. | |
| 9873 | 388 |
| 10292 | 389 * The `ismatrix' function now returns true for all numeric, |

390 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 391 returned false if the first or second dimension was zero. |
| 392 Hence, `ismatrix ([])' was false, | |
| 393 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 394 |
| 10118 | 395 * The `issquare' function now returns a logical scalar, and is |
| 396 equivalent to the expression | |
| 397 | |
| 398 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 399 | |
| 400 The dimension is no longer returned. As a result, `issquare ([])' | |
| 401 now yields true. | |

| 10118 | 403 * The `issymmetric' function now checks for symmetry instead of |

404 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 405 logical scalar is returned rather than the dimension, so |
| 406 `issymmetric ([])' is now true. | |
| 9873 | 407 |
| 10118 | 408 ** Function handles are now aware of overloaded functions. If a |
| 409 function is overloaded, the handle determines at the time of its | |
| 410 reference which function to call. A non-overloaded version does not | |
| 411 need to exist. | |
| 9873 | 412 |
| 10118 | 413 ** Overloading functions for built-in classes (double, int8, cell, |
| 414 etc.) is now compatible with Matlab. | |
| 9408 | 415 |
| 10323 | 416 ** Function handles can now be compared with the == and != operators, |
| 417 as well as the `isequal' function. | |
| 418 | |
| 10118 | 419 ** Performance of concatenation (using []) and the functions `cat', |
| 420 `horzcat', and `vertcat' has been improved for multidimensional | |
| 421 arrays. | |
| 10117 | 422 |
| 9547 | 423 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 424 efficiently in certain cases. For instance, if M is a matrix and S a |
| 425 scalar, then the statement | |
| 9547 | 426 |
| 10118 | 427 M += S; |
| 9547 | 428 |
| 10118 | 429 will operate on M's data in-place if it is not shared by another |
| 430 variable, usually increasing both time and memory efficiency. | |
| 9547 | 431 |
| 9558 | 432 Only selected common combinations are affected, namely: |
| 9547 | 433 |
| 434 matrix += matrix | |
| 435 matrix -= matrix | |
| 9558 | 436 matrix .*= matrix |
| 437 matrix ./= matrix | |
| 438 | |
| 9547 | 439 matrix += scalar |
| 440 matrix -= scalar | |
| 441 matrix *= scalar | |
| 442 matrix /= scalar | |
| 9558 | 443 |
| 9552 | 444 logical matrix |= logical matrix |
| 445 logical matrix &= logical matrix | |
| 9547 | 446 |
| 10118 | 447 where matrix and scalar belong to the same class. The left-hand |
| 448 side must be a simple variable reference. | |
| 9888 | 449 |
| 10118 | 450 Moreover, when unary operators occur in expressions, Octave will |
| 451 also try to do the operation in-place if it's argument is a | |

452 temporary expression. |
| 9589 | 453 |
| 10118 | 454 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 455 complex numbers has changed to be consistent with the strict | |
| 456 ordering defined by the `max', `min', and `sort' functions. More | |
| 457 specifically, complex numbers are compared by lexicographical | |
| 458 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 459 parts were compared; this can be trivially achieved by converting |
| 460 the operands to real values with the `real' function. | |
| 9547 | 461 |
| 10118 | 462 ** The automatic simplification of complex computation results has |
| 463 changed. Octave will now simplify any complex number with a zero | |
| 464 imaginary part or any complex matrix with all elements having zero | |
| 465 imaginary part to a real value. Previously, this was done only for | |
| 466 positive zeros. Note that the behavior of the complex function is | |
| 467 unchanged and it still produces a complex value even if the | |
| 468 imaginary part is zero. | |
| 9826 | 469 |
| 10118 | 470 ** As a side effect of code refactoring in liboctave, the binary |
| 471 logical operations are now more easily amenable to compiler | |
| 472 optimizations and are thus significantly faster. | |
| 9595 | 473 |
| 10118 | 474 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 475 redundant copies. For more information, see the manual. | |
| 9595 | 476 |
| 10453 | 477 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 478 handle the expressions |

482 V / M |
| 9664 | 483 |
| 10118 | 484 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 485 In particular, if M is triangular, all three expressions will be | |
| 486 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 487 flags. Previously, all three expressions required a physical |
| 10118 | 488 transpose of M. |
| 9664 | 489 |
| 10118 | 490 ** More efficient handling of certain mixed real-complex matrix |
| 491 operations. For instance, if RM is a real matrix and CM a complex | |
| 492 matrix, | |
| 9664 | 493 |
| 10118 | 494 RM * CM |
| 9664 | 495 |
| 496 can now be evaluated either as | |
| 497 | |
| 498 complex (RM * real (CM), RM * imag (CM)) | |
| 499 | |
| 500 or as | |
| 501 | |
| 502 complex (RM) * CM, | |
| 503 | |
| 10453 | 504 depending on the dimensions. The first form requires more |
| 505 temporaries and copying, but halves the FLOP count, which normally | |
| 506 brings better performance if RM has enough rows. Previously, the | |
| 507 second form was always used. | |
| 9664 | 508 |
| 11111 | 509 Matrix division is similarly affected. |
| 9664 | 510 |
| 10118 | 511 ** More efficient handling of triangular matrix factors returned from |
| 512 factorizations. The functions for computing QR, LU and Cholesky | |
| 513 factorizations will now automatically return the triangular matrix | |
| 514 factors with proper internal matrix_type set, so that it won't need | |
| 515 to be computed when the matrix is used for division. | |
| 9717 | 516 |
| 10118 | 517 ** The built-in `sum' function now handles the non-native summation |
| 518 (i.e., double precision sum of single or integer inputs) more | |
| 519 efficiently, avoiding a temporary conversion of the whole input | |
| 520 array to doubles. Further, `sum' can now accept an extra option | |
| 521 argument, using a compensated summation algorithm rather than a | |
| 522 straightforward sum, which significantly improves precision if lots | |
| 523 of cancellation occurs in the summation. | |
| 9717 | 524 |
| 10118 | 525 ** The built-in `bsxfun' function now uses optimized code for certain |
| 526 cases where built-in operator handles are passed in. Namely, the | |
| 527 optimizations concern the operators `plus', `minus', `times', | |
| 528 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 529 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 530 functions `min' and `max'. Optimizations only apply when both | |
| 531 operands are of the same built-in class. Mixed real/complex and | |
| 532 single/double operations will first convert both operands to a | |
| 533 common type. | |
| 9745 | 534 |
| 10118 | 535 ** The `strfind' and `strrep' functions now have compiled |
| 536 implementations, facilitating significantly more efficient searching | |
| 537 and replacing in strings, especially with longer patterns. The code | |
| 538 of `strcat' has been vectorized and is now much more efficient when | |
| 539 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 540 functions are now built-in functions, providing better performance. | |

545 has been removed. |
| 10208 | 546 |
| 10453 | 547 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 548 tilde (~) is now supported. Ignored output arguments may be |
| 549 detected from a function using the built-in function `isargout'. | |
| 550 For more details, consult the manual. | |
| 10886 | 551 |
| 10453 | 552 ** The list datatype, deprecated since the introduction of cells, has |
| 553 been removed. | |
| 10276 | 554 |
| 10453 | 555 ** The accumarray function has been optimized and is now significantly |
| 556 faster in certain important cases. | |
| 10054 | 557 |
| 10292 | 558 ** The behavior of isreal and isnumeric functions was changed to be more |
| 559 Matlab-compatible. | |
| 560 | |
| 10406 | 561 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 562 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 563 Octave:int-math-overflow) have been removed. |
| 10406 | 564 |
| 10453 | 565 ** rem and mod are now built-in functions. They also handle integer |
| 566 types efficiently using integer arithmetic. | |
| 10437 | 567 |
| 10536 | 568 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 569 Since Octave uses compressed column storage for sparse matrices, | |
| 570 major attention is devoted to operations manipulating whole columns. | |
| 571 Such operations are now significantly faster, as well as some other | |
| 572 important cases. | |
| 573 | |
| 574 Further, it is now possible to pre-allocate a sparse matrix and | |
| 575 subsequently fill it by assignments, provided they meet certain | |
| 576 conditions. For more information, consult the `spalloc' function, | |
| 577 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 578 longer always equal in Octave. Octave may also produce a matrix |
| 579 with nnz < nzmax as a result of other operations, so you should | |

580 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 581 space allocated for nonzero elements). |
| 10536 | 582 |
| 583 Sparse concatenation is also affected, and concatenating sparse | |
| 584 matrices, especially larger collections, is now significantly more | |
| 11111 | 585 efficient. This applies to both the [] operator and the |
| 10536 | 586 cat/vertcat/horzcat functions. |
| 587 | |
| 11111 | 588 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 589 for computing the singular value decomposition using svd, instead |
| 11111 | 590 of the default xGESVD, using the configuration pseudo-variable |
| 591 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 592 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 593 robust on highly ill-conditioned matrices. |
| 594 | |
| 595 ** Configuration pseudo-variables, such as page_screen_output or | |
| 596 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 597 accept a "local" option as second argument, requesting the change | |

811 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 812 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 813 removed from Octave. These function were incompatible with the | |
| 814 high level graphics handle code. | |
| 6329 | 815 |
| 8885 | 816 ** The Control, Finance and Quaternion functions have been removed. |
| 817 | |
| 818 These functions are now available as separate packages from | |
| 819 | |
| 820 http://octave.sourceforge.net/packages.html | |
| 821 | |
| 822 and can be reinstalled using the Octave package manager (see | |
| 823 the pkg function). | |
| 824 | |
| 825 ** Specific sparse matrix functions removed. | |
| 826 | |
| 827 The following functions, which handled only sparse matrices have | |
| 828 been removed. Instead of calling these functions directly, you | |
| 829 should use the corresponding function without the "sp" prefix. | |
| 8737 | 830 |

| 835 spcumprod spinv spmin | |
| 836 | |
| 837 ** Improvements to the debugger. | |
| 838 | |
| 839 The interactive debugging features have been improved. Stopping | |
| 840 on statements with dbstop should work correctly now. Stepping | |
| 841 into and over functions, and stepping one statement at a time | |
| 842 (with dbstep) now works. Moving up and down the call stack with | |
| 843 dbup and dbdown now works. The dbstack function is now available | |
| 844 to print the current function call stack. The new dbquit function | |
| 845 is available to exit the debugging mode. | |
| 846 | |
| 847 ** Improved traceback error messages. | |
| 848 | |
| 849 Traceback error messages are much more concise and easier to | |
| 850 understand. They now display information about the function call | |
| 851 stack instead of the stack of all statements that were active at | |
| 852 the point of the error. | |

855 |
| 8737 | 856 Octave now includes OOP features and the user can create their own |
| 857 class objects and overloaded functions and operators. For | |
| 858 example, all methods of a class called "myclass" will be found in | |
| 859 a directory "@myclass" on the users path. The class specific | |
| 860 versions of functions and operators take precedence over the | |
| 861 generic versions of these functions. | |
| 862 | |
| 863 New functions related to OOP include | |
| 7189 | 864 |
| 8737 | 865 class inferiorto isobject loadobj methods superiorto |
| 866 | |
| 867 See the Octave manual for more details. | |
| 7038 | 868 |
| 8747 | 869 ** Parsing of Command-style Functions. |
| 870 | |
| 871 Octave now parses command-style functions without needing to first | |
| 872 declare them with "mark_as_command". The rules for recognizing a | |
| 873 command-style function calls are | |
| 874 | |
| 875 * A command must appear as the first word in a statement, | |
| 876 followed by a space. | |
| 877 | |
| 878 * The first character after the space must not be '=' or '(' | |
| 879 | |
| 880 * The next token after the space must not look like a binary | |
| 881 operator. | |
| 882 | |
| 883 These rules should be mostly compatible with the way Matlab parses | |
| 884 command-style function calls and allow users to define commands in | |
| 885 .m files without having to mark them as commands. | |
| 886 | |
| 887 Note that previous versions of Octave allowed expressions like | |
| 888 | |
| 889 x = load -text foo.dat | |
| 890 | |
| 891 but an expression like this will now generate a parse error. In | |
| 892 order to assign the value returned by a function to a variable, | |
| 893 you must use the normal function call syntax: | |
| 894 | |
| 895 x = load ("-text", "foo.dat"); | |
| 896 | |
| 8737 | 897 ** Block comments. |
| 898 | |
| 8747 | 899 Commented code can be between matching "#{" and "#}" or "%{" and |
| 900 "%}" markers, even if the commented code spans several line. This | |
| 901 allows blocks code to be commented, without needing to comment | |
| 902 each line. For example, | |
| 5814 | 903 |
| 8747 | 904 function [s, t] = func (x, y) |
| 905 s = 2 * x; | |
| 906 #{ | |
| 907 s *= y; | |
| 908 t = y + x; | |
| 909 #} | |

965 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 966 both time and memory consumption. |
| 9128 | 967 Also, Octave will now attempt to detect and optimize usage of a vector |
| 968 as a stack, when elements are being repeatedly inserted at/removed from | |
| 969 the end of the vector. | |

| 8755 | 973 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all, |

| 978 The performance of sort has been improved, especially when sorting | |

| 980 implementation was added. The sortrows function now uses a more | |

981 efficient algorithm, especially in the homogeneous case. The lookup |
| 10453 | 982 function is now a built-in function performing a binary search, |
| 983 optimized for long runs of close elements. Lookup also works with | |
| 984 cell arrays of strings. | |

| 986 ** Range arithmetics | |

990 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 991 increment are allowed and can be constructed using the built-in |
| 992 function `ones'. | |
| 9006 | 993 |
| 994 ** Various performance improvements. | |
| 995 | |
| 10453 | 996 Performance of a number of other built-in operations and functions |
| 997 was improved, including: | |
| 9006 | 998 |
| 999 * logical operations | |
| 1000 * comparison operators | |
| 1001 * element-wise power | |
| 1002 * accumarray | |
| 1003 * cellfun | |
| 1004 * isnan | |
| 1005 * isinf | |
| 1006 * isfinite | |
| 1007 * nchoosek | |
| 1008 * repmat | |
| 1009 * strcmp | |
| 1010 | |
| 8737 | 1011 ** 64-bit integer arithmetic. |
| 1012 | |
| 1013 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1014 supported, with saturation semantics like the other integer types. | |
| 1015 Performance of most integer arithmetic operations has been | |
| 1016 improved by using integer arithmetic directly. Previously, Octave | |
| 1017 performed integer math with saturation semantics by converting the | |
| 1018 operands to double precision, performing the operation, and then | |
| 1019 converting the result back to an integer value, truncating if | |
| 1020 necessary. | |
| 1021 | |
| 8885 | 1022 ** Diagonal and permutation matrices. |
| 1023 | |
| 1024 The interpreter can now treat diagonal and permutation matrices as | |
| 1025 special objects that store only the non-zero elements, rather than | |
| 1026 general full matrices. Therefore, it is now possible to construct | |
| 1027 and use these matrices in linear algebra without suffering a | |
| 1028 performance penalty due to storing large numbers of zero elements. | |
| 1029 | |
| 1030 ** Improvements to fsolve. | |
| 1031 | |
| 1032 The fsolve function now accepts an option structure argument (see | |
| 1033 also the optimset function). The INFO values returned from fsolve | |
| 1034 have changed to be compatible with Matlab's fsolve function. | |
| 1035 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1036 complex-differentiable complex systems, systems with a sparse | |
| 1037 jacobian and can work in single precision if given single precision | |

| 1041 | |
| 1042 The norm function is now able to compute row or column norms of a | |
| 1043 matrix in a single call, as well as general matrix p-norms. | |
| 1044 | |
| 1045 ** New functions for computing some eigenvalues or singular values. | |
| 1046 | |
| 1047 The eigs and svds functions have been included in Octave. These | |
| 1048 functions require the ARPACK library (now distributed under a | |

| 1093 | |
| 1094 The strcat function is now compatible with Matlab's strcat | |

| 1097 | |
| 1098 strcat ('foo ', 'bar') | |

| 1110 to generate cache files for external packages when they are | |
