| 10118 | 310 ** The `lookup' function was extended to be more useful for |
| 311 general-purpose binary searching. Using this improvement, the | |
| 312 ismember function was rewritten for significantly better | |
| 313 performance. | |
| 9352 | 314 |
| 315 ** Real, integer and logical matrices, when used in indexing, will now | |
| 316 cache the internal index_vector value (zero-based indices) when | |
| 317 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 318 subsequent indexing by the same matrix. In particular, this means it |
| 319 is no longer needed to avoid repeated indexing by logical arrays | |
| 320 using find for performance reasons. | |
| 9888 | 321 |
| 10118 | 322 ** Logical matrices are now treated more efficiently when used as |
| 323 indices. Octave will keep the index as a logical mask unless the | |
| 324 ratio of true elements is small enough, using a specialized | |
| 325 code. Previously, all logical matrices were always first converted | |
| 326 to index vectors. This results in savings in both memory and | |
| 327 computing time. | |
| 9480 | 328 |
| 10118 | 329 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 330 functions for better performance. These functions are now faster, | |
| 331 can deliver more economized results for ranges, and can reuse the | |
| 332 index cache mechanism described in previous paragraph. | |
| 333 | |
| 334 ** The built-in function equivalents to associative operators (`plus', | |
| 335 `times', `mtimes', `and', and `or') have been extended to accept | |
| 336 multiple arguments. This is especially useful for summing | |
| 337 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 338 |
| 9449 | 339 matrix_sum = plus (matrix_list{:}); |
| 340 | |
| 10118 | 341 ** An FTP object type based on libcurl has been implemented. These |
| 342 objects allow ftp connections, downloads and uploads to be | |
| 343 managed. For example, | |
| 9880 | 344 |
| 10118 | 345 fp = ftp ("ftp.octave.org); |
| 346 cd (fp, "gnu/octave"); | |
| 347 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 348 close (fp); | |
| 9880 | 349 |
| 10118 | 350 ** The default behavior of `assert (observed, expected)' has been |
| 351 relaxed to employ less strict checking that does not require the | |
| 352 internals of the values to match. This avoids previously valid | |
| 353 tests from breaking due to new internal classes introduced in future | |
| 354 Octave versions. | |
| 9449 | 355 |
| 356 For instance, all of these assertions were true in Octave 3.0.x | |
| 357 but false in 3.2.x due to new optimizations and improvements: | |
| 358 | |
| 359 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 360 assert (zeros (0, 0), []) | |
| 361 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 362 |
| 10118 | 363 ** The behavior of library functions `ismatrix', `issquare', and |
| 364 `issymmetric' has been changed for better consistency. | |
| 9873 | 365 |
| 10292 | 366 * The `ismatrix' function now returns true for all numeric, |
|

367 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 368 returned false if the first or second dimension was zero. |

381 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 382 logical scalar is returned rather than the dimension, so |
| 383 `issymmetric ([])' is now true. | |
| 9873 | 384 |
| 10118 | 385 ** Function handles are now aware of overloaded functions. If a |
| 386 function is overloaded, the handle determines at the time of its | |
| 387 reference which function to call. A non-overloaded version does not | |
| 388 need to exist. | |
| 9873 | 389 |
| 10118 | 390 ** Overloading functions for built-in classes (double, int8, cell, |
| 391 etc.) is now compatible with Matlab. | |
| 9408 | 392 |
| 10323 | 393 ** Function handles can now be compared with the == and != operators, |
| 394 as well as the `isequal' function. | |
| 395 | |
| 10118 | 396 ** Performance of concatenation (using []) and the functions `cat', |
| 397 `horzcat', and `vertcat' has been improved for multidimensional | |
| 398 arrays. | |
| 10117 | 399 |
| 9547 | 400 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 401 efficiently in certain cases. For instance, if M is a matrix and S a |
| 402 scalar, then the statement | |
| 9547 | 403 |
| 10118 | 404 M += S; |
| 9547 | 405 |
| 10118 | 406 will operate on M's data in-place if it is not shared by another |
| 407 variable, usually increasing both time and memory efficiency. | |
| 9547 | 408 |
| 9558 | 409 Only selected common combinations are affected, namely: |
| 9547 | 410 |
| 411 matrix += matrix | |
| 412 matrix -= matrix | |
| 9558 | 413 matrix .*= matrix |
| 414 matrix ./= matrix | |
| 415 | |
| 9547 | 416 matrix += scalar |
| 417 matrix -= scalar | |
| 418 matrix *= scalar | |
| 419 matrix /= scalar | |
| 9558 | 420 |
| 9552 | 421 logical matrix |= logical matrix |
| 422 logical matrix &= logical matrix | |
| 9547 | 423 |
| 10118 | 424 where matrix and scalar belong to the same class. The left-hand |
| 425 side must be a simple variable reference. | |
| 9888 | 426 |
| 10118 | 427 Moreover, when unary operators occur in expressions, Octave will |
| 428 also try to do the operation in-place if it's argument is a | |

429 temporary expression. |
| 9589 | 430 |
| 10118 | 431 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 432 complex numbers has changed to be consistent with the strict | |
| 433 ordering defined by the `max', `min', and `sort' functions. More | |
| 434 specifically, complex numbers are compared by lexicographical | |
| 435 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 436 parts were compared; this can be trivially achieved by converting |
| 437 the operands to real values with the `real' function. | |
| 9547 | 438 |
| 10118 | 439 ** The automatic simplification of complex computation results has |
| 440 changed. Octave will now simplify any complex number with a zero | |
| 441 imaginary part or any complex matrix with all elements having zero | |
| 442 imaginary part to a real value. Previously, this was done only for | |
| 443 positive zeros. Note that the behavior of the complex function is | |
| 444 unchanged and it still produces a complex value even if the | |
| 445 imaginary part is zero. | |
| 9826 | 446 |
| 10118 | 447 ** As a side effect of code refactoring in liboctave, the binary |
| 448 logical operations are now more easily amenable to compiler | |
| 449 optimizations and are thus significantly faster. | |
| 9595 | 450 |
| 10118 | 451 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 452 redundant copies. For more information, see the manual. | |
| 9595 | 453 |
| 10453 | 454 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 455 handle the expressions |

459 V / M |
| 9664 | 460 |
| 10118 | 461 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 462 In particular, if M is triangular, all three expressions will be | |
| 463 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 464 flags. Previously, all three expressions required a physical |
| 10118 | 465 transpose of M. |
| 9664 | 466 |
| 10118 | 467 ** More efficient handling of certain mixed real-complex matrix |
| 468 operations. For instance, if RM is a real matrix and CM a complex | |
| 469 matrix, | |
| 9664 | 470 |
| 10118 | 471 RM * CM |
| 9664 | 472 |
| 473 can now be evaluated either as | |
| 474 | |
| 475 complex (RM * real (CM), RM * imag (CM)) | |
| 476 | |
| 477 or as | |
| 478 | |
| 479 complex (RM) * CM, | |
| 480 | |
| 10453 | 481 depending on the dimensions. The first form requires more |
| 482 temporaries and copying, but halves the FLOP count, which normally | |
| 483 brings better performance if RM has enough rows. Previously, the | |
| 484 second form was always used. | |
| 9664 | 485 |
| 11111 | 486 Matrix division is similarly affected. |
| 9664 | 487 |
| 10118 | 488 ** More efficient handling of triangular matrix factors returned from |
| 489 factorizations. The functions for computing QR, LU and Cholesky | |
| 490 factorizations will now automatically return the triangular matrix | |
| 491 factors with proper internal matrix_type set, so that it won't need | |
| 492 to be computed when the matrix is used for division. | |
| 9717 | 493 |
| 10118 | 494 ** The built-in `sum' function now handles the non-native summation |
| 495 (i.e., double precision sum of single or integer inputs) more | |
| 496 efficiently, avoiding a temporary conversion of the whole input | |
| 497 array to doubles. Further, `sum' can now accept an extra option | |
| 498 argument, using a compensated summation algorithm rather than a | |
| 499 straightforward sum, which significantly improves precision if lots | |
| 500 of cancellation occurs in the summation. | |
| 9717 | 501 |
| 10118 | 502 ** The built-in `bsxfun' function now uses optimized code for certain |
| 503 cases where built-in operator handles are passed in. Namely, the | |
| 504 optimizations concern the operators `plus', `minus', `times', | |
| 505 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 506 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 507 functions `min' and `max'. Optimizations only apply when both | |
| 508 operands are of the same built-in class. Mixed real/complex and | |
| 509 single/double operations will first convert both operands to a | |
| 510 common type. | |
| 9745 | 511 |
| 10118 | 512 ** The `strfind' and `strrep' functions now have compiled |
| 513 implementations, facilitating significantly more efficient searching | |
| 514 and replacing in strings, especially with longer patterns. The code | |
| 515 of `strcat' has been vectorized and is now much more efficient when | |
| 516 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 517 functions are now built-in functions, providing better performance. | |

| 10453 | 524 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 525 tilde (~) is now supported. Ignored output arguments may be |
| 526 detected from a function using the built-in function `isargout'. | |
| 527 For more details, consult the manual. | |
| 10886 | 528 |
| 10453 | 529 ** The list datatype, deprecated since the introduction of cells, has |
| 530 been removed. | |

| 10453 | 532 ** The accumarray function has been optimized and is now significantly |

| 539 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 540 Octave:int-math-overflow) have been removed. |
| 10406 | 541 |
| 10453 | 542 ** rem and mod are now built-in functions. They also handle integer |
| 543 types efficiently using integer arithmetic. | |
| 10437 | 544 |
| 10536 | 545 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 546 Since Octave uses compressed column storage for sparse matrices, | |
| 547 major attention is devoted to operations manipulating whole columns. | |
| 548 Such operations are now significantly faster, as well as some other | |
| 549 important cases. | |
| 550 | |
| 551 Further, it is now possible to pre-allocate a sparse matrix and | |
| 552 subsequently fill it by assignments, provided they meet certain | |
| 553 conditions. For more information, consult the `spalloc' function, | |
| 554 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 555 longer always equal in Octave. Octave may also produce a matrix |
| 556 with nnz < nzmax as a result of other operations, so you should | |

557 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 558 space allocated for nonzero elements). |
| 10536 | 559 |
| 560 Sparse concatenation is also affected, and concatenating sparse | |
| 561 matrices, especially larger collections, is now significantly more | |
| 11111 | 562 efficient. This applies to both the [] operator and the |
| 10536 | 563 cat/vertcat/horzcat functions. |
| 564 | |
| 11111 | 565 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 566 for computing the singular value decomposition using svd, instead |
| 11111 | 567 of the default xGESVD, using the configuration pseudo-variable |
| 568 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 569 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 570 robust on highly ill-conditioned matrices. |
| 571 | |
| 572 ** Configuration pseudo-variables, such as page_screen_output or | |
| 573 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |

| 816 The interactive debugging features have been improved. Stopping | |
| 817 on statements with dbstop should work correctly now. Stepping | |
| 818 into and over functions, and stepping one statement at a time | |
| 819 (with dbstep) now works. Moving up and down the call stack with | |
| 820 dbup and dbdown now works. The dbstack function is now available | |
| 821 to print the current function call stack. The new dbquit function | |
| 822 is available to exit the debugging mode. | |
| 823 | |
| 824 ** Improved traceback error messages. | |
| 825 | |
| 826 Traceback error messages are much more concise and easier to | |
| 827 understand. They now display information about the function call | |
| 828 stack instead of the stack of all statements that were active at | |
| 829 the point of the error. | |

832 |
| 8737 | 833 Octave now includes OOP features and the user can create their own |
| 834 class objects and overloaded functions and operators. For | |
| 835 example, all methods of a class called "myclass" will be found in | |
| 836 a directory "@myclass" on the users path. The class specific | |
| 837 versions of functions and operators take precedence over the | |
| 838 generic versions of these functions. | |
| 839 | |
| 840 New functions related to OOP include | |
| 7189 | 841 |
| 8737 | 842 class inferiorto isobject loadobj methods superiorto |
| 843 | |
| 844 See the Octave manual for more details. | |
| 7038 | 845 |
| 8747 | 846 ** Parsing of Command-style Functions. |
| 847 | |
| 848 Octave now parses command-style functions without needing to first | |
| 849 declare them with "mark_as_command". The rules for recognizing a | |
| 850 command-style function calls are | |
| 851 | |
| 852 * A command must appear as the first word in a statement, | |
| 853 followed by a space. | |
| 854 | |
| 855 * The first character after the space must not be '=' or '(' | |
| 856 | |
| 857 * The next token after the space must not look like a binary | |
| 858 operator. | |
| 859 | |
| 860 These rules should be mostly compatible with the way Matlab parses | |
| 861 command-style function calls and allow users to define commands in | |
| 862 .m files without having to mark them as commands. | |
| 863 | |
| 864 Note that previous versions of Octave allowed expressions like | |
| 865 | |
| 866 x = load -text foo.dat | |
| 867 | |
| 868 but an expression like this will now generate a parse error. In | |
| 869 order to assign the value returned by a function to a variable, | |
| 870 you must use the normal function call syntax: | |
| 871 | |
| 872 x = load ("-text", "foo.dat"); | |
| 873 | |
| 8737 | 874 ** Block comments. |
| 875 | |
| 8747 | 876 Commented code can be between matching "#{" and "#}" or "%{" and |
| 877 "%}" markers, even if the commented code spans several line. This | |
| 878 allows blocks code to be commented, without needing to comment | |
| 879 each line. For example, | |
| 5814 | 880 |
| 8747 | 881 function [s, t] = func (x, y) |
| 882 s = 2 * x; | |
| 883 #{ | |
| 884 s *= y; | |
| 885 t = y + x; | |
| 886 #} | |

942 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 943 both time and memory consumption. |
| 9128 | 944 Also, Octave will now attempt to detect and optimize usage of a vector |
| 945 as a stack, when elements are being repeatedly inserted at/removed from | |
| 946 the end of the vector. | |

967 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 968 increment are allowed and can be constructed using the built-in |
| 969 function `ones'. | |
| 9006 | 970 |
| 971 ** Various performance improvements. | |
| 972 | |
| 10453 | 973 Performance of a number of other built-in operations and functions |
| 974 was improved, including: | |
| 9006 | 975 |
| 976 * logical operations | |
| 977 * comparison operators | |
| 978 * element-wise power | |
| 979 * accumarray | |
| 980 * cellfun | |
| 981 * isnan | |
| 982 * isinf | |
| 983 * isfinite | |
| 984 * nchoosek | |
| 985 * repmat | |
| 986 * strcmp | |
| 987 | |
| 8737 | 988 ** 64-bit integer arithmetic. |
| 989 | |
| 990 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 991 supported, with saturation semantics like the other integer types. | |
| 992 Performance of most integer arithmetic operations has been | |
| 993 improved by using integer arithmetic directly. Previously, Octave | |
| 994 performed integer math with saturation semantics by converting the | |
| 995 operands to double precision, performing the operation, and then | |
| 996 converting the result back to an integer value, truncating if | |
| 997 necessary. | |
| 998 | |
| 8885 | 999 ** Diagonal and permutation matrices. |
| 1000 | |
| 1001 The interpreter can now treat diagonal and permutation matrices as | |
| 1002 special objects that store only the non-zero elements, rather than | |
| 1003 general full matrices. Therefore, it is now possible to construct | |
| 1004 and use these matrices in linear algebra without suffering a | |
| 1005 performance penalty due to storing large numbers of zero elements. | |
| 1006 | |
| 1007 ** Improvements to fsolve. | |
| 1008 | |
| 1009 The fsolve function now accepts an option structure argument (see | |
| 1010 also the optimset function). The INFO values returned from fsolve | |
| 1011 have changed to be compatible with Matlab's fsolve function. | |
| 1012 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1013 complex-differentiable complex systems, systems with a sparse | |
| 1014 jacobian and can work in single precision if given single precision | |

| 8885 | 1069 ** Changes to strcat. |
| 1070 | |
| 1071 The strcat function is now compatible with Matlab's strcat | |
| 1072 function, which removes trailing whitespace when concatenating | |
| 1073 character strings. For example | |
| 1074 | |
| 1075 strcat ('foo ', 'bar') | |
| 1076 ==> 'foobar' | |
| 1077 | |
| 1078 The new function cstrcat provides the previous behavior of | |
| 1079 Octave's strcat. | |
| 1080 | |
| 1081 ** Improvements to the help functions. | |

1083 The help system has been mostly re-implemented in .m files to make |
| 8885 | 1084 it easier to modify. Performance of the lookfor function has been |
| 1085 greatly improved by caching the help text from all functions that | |
| 1086 are distributed with Octave. The pkg function has been modified | |
| 1087 to generate cache files for external packages when they are | |
| 1088 installed. | |
