| 10118 | 421 ** The `lookup' function was extended to be more useful for |
| 422 general-purpose binary searching. Using this improvement, the | |
| 423 ismember function was rewritten for significantly better | |
| 424 performance. | |
| 9352 | 425 |
| 426 ** Real, integer and logical matrices, when used in indexing, will now | |
| 427 cache the internal index_vector value (zero-based indices) when | |
| 428 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 429 subsequent indexing by the same matrix. In particular, this means it |
| 430 is no longer needed to avoid repeated indexing by logical arrays | |
| 431 using find for performance reasons. | |
| 9888 | 432 |
| 10118 | 433 ** Logical matrices are now treated more efficiently when used as |
| 434 indices. Octave will keep the index as a logical mask unless the | |
| 435 ratio of true elements is small enough, using a specialized | |
| 436 code. Previously, all logical matrices were always first converted | |
| 437 to index vectors. This results in savings in both memory and | |
| 438 computing time. | |
| 9480 | 439 |
| 10118 | 440 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 441 functions for better performance. These functions are now faster, | |
| 442 can deliver more economized results for ranges, and can reuse the | |
| 443 index cache mechanism described in previous paragraph. | |
| 444 | |
| 445 ** The built-in function equivalents to associative operators (`plus', | |
| 446 `times', `mtimes', `and', and `or') have been extended to accept | |
| 447 multiple arguments. This is especially useful for summing | |
| 448 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 449 |
| 9449 | 450 matrix_sum = plus (matrix_list{:}); |
| 451 | |
| 10118 | 452 ** An FTP object type based on libcurl has been implemented. These |
| 453 objects allow ftp connections, downloads and uploads to be | |
| 454 managed. For example, | |
| 9880 | 455 |
| 10118 | 456 fp = ftp ("ftp.octave.org); |
| 457 cd (fp, "gnu/octave"); | |
| 458 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 459 close (fp); | |
| 9880 | 460 |
| 10118 | 461 ** The default behavior of `assert (observed, expected)' has been |
| 462 relaxed to employ less strict checking that does not require the | |
| 463 internals of the values to match. This avoids previously valid | |
| 464 tests from breaking due to new internal classes introduced in future | |
| 465 Octave versions. | |
| 9449 | 466 |
| 467 For instance, all of these assertions were true in Octave 3.0.x | |
| 468 but false in 3.2.x due to new optimizations and improvements: | |
| 469 | |
| 470 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 471 assert (zeros (0, 0), []) | |
| 472 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 473 |
| 10118 | 474 ** The behavior of library functions `ismatrix', `issquare', and |
| 475 `issymmetric' has been changed for better consistency. | |
| 9873 | 476 |
| 10292 | 477 * The `ismatrix' function now returns true for all numeric, |

478 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 479 returned false if the first or second dimension was zero. |
| 480 Hence, `ismatrix ([])' was false, | |
| 481 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 482 |
| 10118 | 483 * The `issquare' function now returns a logical scalar, and is |
| 484 equivalent to the expression | |
| 485 | |
| 486 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 487 | |
| 488 The dimension is no longer returned. As a result, `issquare ([])' | |
| 489 now yields true. | |
| 9873 | 490 |
| 10118 | 491 * The `issymmetric' function now checks for symmetry instead of |

492 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 493 logical scalar is returned rather than the dimension, so |
| 494 `issymmetric ([])' is now true. | |
| 9873 | 495 |
| 10118 | 496 ** Function handles are now aware of overloaded functions. If a |
| 497 function is overloaded, the handle determines at the time of its | |
| 498 reference which function to call. A non-overloaded version does not | |
| 499 need to exist. | |
| 9873 | 500 |
| 10118 | 501 ** Overloading functions for built-in classes (double, int8, cell, |
| 502 etc.) is now compatible with Matlab. | |
| 9408 | 503 |
| 10323 | 504 ** Function handles can now be compared with the == and != operators, |
| 505 as well as the `isequal' function. | |
| 506 | |
| 10118 | 507 ** Performance of concatenation (using []) and the functions `cat', |
| 508 `horzcat', and `vertcat' has been improved for multidimensional | |
| 509 arrays. | |
| 10117 | 510 |
| 9547 | 511 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 512 efficiently in certain cases. For instance, if M is a matrix and S a |
| 513 scalar, then the statement | |
| 9547 | 514 |
| 10118 | 515 M += S; |
| 9547 | 516 |
| 10118 | 517 will operate on M's data in-place if it is not shared by another |
| 518 variable, usually increasing both time and memory efficiency. | |
| 9547 | 519 |
| 9558 | 520 Only selected common combinations are affected, namely: |
| 9547 | 521 |
| 522 matrix += matrix | |
| 523 matrix -= matrix | |
| 9558 | 524 matrix .*= matrix |
| 525 matrix ./= matrix | |
| 526 | |
| 9547 | 527 matrix += scalar |
| 528 matrix -= scalar | |
| 529 matrix *= scalar | |
| 530 matrix /= scalar | |
| 9558 | 531 |
| 9552 | 532 logical matrix |= logical matrix |
| 533 logical matrix &= logical matrix | |
| 9547 | 534 |
| 10118 | 535 where matrix and scalar belong to the same class. The left-hand |
| 536 side must be a simple variable reference. | |
| 9888 | 537 |
| 10118 | 538 Moreover, when unary operators occur in expressions, Octave will |
| 539 also try to do the operation in-place if it's argument is a | |

540 temporary expression. |
| 9589 | 541 |
| 10118 | 542 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 543 complex numbers has changed to be consistent with the strict | |
| 544 ordering defined by the `max', `min', and `sort' functions. More | |
| 545 specifically, complex numbers are compared by lexicographical | |
| 546 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 547 parts were compared; this can be trivially achieved by converting |
| 548 the operands to real values with the `real' function. | |
| 9547 | 549 |
| 10118 | 550 ** The automatic simplification of complex computation results has |
| 551 changed. Octave will now simplify any complex number with a zero | |
| 552 imaginary part or any complex matrix with all elements having zero | |
| 553 imaginary part to a real value. Previously, this was done only for | |
| 554 positive zeros. Note that the behavior of the complex function is | |
| 555 unchanged and it still produces a complex value even if the | |
| 556 imaginary part is zero. | |
| 9826 | 557 |
| 10118 | 558 ** As a side effect of code refactoring in liboctave, the binary |
| 559 logical operations are now more easily amenable to compiler | |
| 560 optimizations and are thus significantly faster. | |
| 9595 | 561 |
| 10118 | 562 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 563 redundant copies. For more information, see the manual. | |

570 V / M |
| 9664 | 571 |
| 10118 | 572 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 573 In particular, if M is triangular, all three expressions will be | |
| 574 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 575 flags. Previously, all three expressions required a physical |
| 10118 | 576 transpose of M. |
| 9664 | 577 |
| 10118 | 578 ** More efficient handling of certain mixed real-complex matrix |
| 579 operations. For instance, if RM is a real matrix and CM a complex | |
| 580 matrix, | |
| 9664 | 581 |
| 10118 | 582 RM * CM |
| 9664 | 583 |
| 584 can now be evaluated either as | |
| 585 | |
| 586 complex (RM * real (CM), RM * imag (CM)) | |
| 587 | |
| 588 or as | |
| 589 | |
| 590 complex (RM) * CM, | |
| 591 | |
| 10453 | 592 depending on the dimensions. The first form requires more |
| 593 temporaries and copying, but halves the FLOP count, which normally | |
| 594 brings better performance if RM has enough rows. Previously, the | |
| 595 second form was always used. | |
| 9664 | 596 |
| 11111 | 597 Matrix division is similarly affected. |
| 9664 | 598 |
| 10118 | 599 ** More efficient handling of triangular matrix factors returned from |
| 600 factorizations. The functions for computing QR, LU and Cholesky | |
| 601 factorizations will now automatically return the triangular matrix | |
| 602 factors with proper internal matrix_type set, so that it won't need | |
| 603 to be computed when the matrix is used for division. | |
| 9717 | 604 |
| 10118 | 605 ** The built-in `sum' function now handles the non-native summation |
| 606 (i.e., double precision sum of single or integer inputs) more | |
| 607 efficiently, avoiding a temporary conversion of the whole input | |
| 608 array to doubles. Further, `sum' can now accept an extra option | |
| 609 argument, using a compensated summation algorithm rather than a | |
| 610 straightforward sum, which significantly improves precision if lots | |
| 611 of cancellation occurs in the summation. | |
| 9717 | 612 |
| 10118 | 613 ** The built-in `bsxfun' function now uses optimized code for certain |
| 614 cases where built-in operator handles are passed in. Namely, the | |
| 615 optimizations concern the operators `plus', `minus', `times', | |
| 616 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 617 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 618 functions `min' and `max'. Optimizations only apply when both | |
| 619 operands are of the same built-in class. Mixed real/complex and | |
| 620 single/double operations will first convert both operands to a | |
| 621 common type. | |
| 9745 | 622 |
| 10118 | 623 ** The `strfind' and `strrep' functions now have compiled |
| 624 implementations, facilitating significantly more efficient searching | |
| 625 and replacing in strings, especially with longer patterns. The code | |
| 626 of `strcat' has been vectorized and is now much more efficient when | |
| 627 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 628 functions are now built-in functions, providing better performance. | |

| 10453 | 635 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 636 tilde (~) is now supported. Ignored output arguments may be |
| 637 detected from a function using the built-in function `isargout'. | |
| 638 For more details, consult the manual. | |
| 10886 | 639 |
| 10453 | 640 ** The list datatype, deprecated since the introduction of cells, has |
| 641 been removed. | |

| 10292 | 646 ** The behavior of isreal and isnumeric functions was changed to be more |
| 647 Matlab-compatible. | |

| 650 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 651 Octave:int-math-overflow) have been removed. |
| 10406 | 652 |
| 10453 | 653 ** rem and mod are now built-in functions. They also handle integer |
| 654 types efficiently using integer arithmetic. | |
| 10437 | 655 |
| 10536 | 656 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 657 Since Octave uses compressed column storage for sparse matrices, | |
| 658 major attention is devoted to operations manipulating whole columns. | |
| 659 Such operations are now significantly faster, as well as some other | |
| 660 important cases. | |
| 661 | |
| 662 Further, it is now possible to pre-allocate a sparse matrix and | |
| 663 subsequently fill it by assignments, provided they meet certain | |
| 664 conditions. For more information, consult the `spalloc' function, | |
| 665 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 666 longer always equal in Octave. Octave may also produce a matrix |
| 667 with nnz < nzmax as a result of other operations, so you should | |

668 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 669 space allocated for nonzero elements). |
| 10536 | 670 |
| 671 Sparse concatenation is also affected, and concatenating sparse | |
| 672 matrices, especially larger collections, is now significantly more | |
| 11111 | 673 efficient. This applies to both the [] operator and the |
| 10536 | 674 cat/vertcat/horzcat functions. |
| 675 | |
| 11111 | 676 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 677 for computing the singular value decomposition using svd, instead |
| 11111 | 678 of the default xGESVD, using the configuration pseudo-variable |
| 679 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 680 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 681 robust on highly ill-conditioned matrices. |
| 682 | |
| 683 ** Configuration pseudo-variables, such as page_screen_output or | |
| 684 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 685 accept a "local" option as second argument, requesting the change | |

899 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 900 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 901 removed from Octave. These function were incompatible with the | |
| 902 high level graphics handle code. | |
| 6329 | 903 |
| 8885 | 904 ** The Control, Finance and Quaternion functions have been removed. |
| 905 | |
| 906 These functions are now available as separate packages from | |
| 907 | |
| 908 http://octave.sourceforge.net/packages.html | |
| 909 | |
| 910 and can be reinstalled using the Octave package manager (see | |
| 911 the pkg function). | |
| 912 | |
| 913 ** Specific sparse matrix functions removed. | |
| 914 | |
| 915 The following functions, which handled only sparse matrices have | |
| 916 been removed. Instead of calling these functions directly, you | |
| 917 should use the corresponding function without the "sp" prefix. | |
| 8737 | 918 |

| 923 spcumprod spinv spmin | |
| 924 | |
| 925 ** Improvements to the debugger. | |
| 926 | |
| 927 The interactive debugging features have been improved. Stopping | |
| 928 on statements with dbstop should work correctly now. Stepping | |
| 929 into and over functions, and stepping one statement at a time | |
| 930 (with dbstep) now works. Moving up and down the call stack with | |
| 931 dbup and dbdown now works. The dbstack function is now available | |
| 932 to print the current function call stack. The new dbquit function | |
| 933 is available to exit the debugging mode. | |
| 934 | |
| 935 ** Improved traceback error messages. | |
| 936 | |
| 937 Traceback error messages are much more concise and easier to | |
| 938 understand. They now display information about the function call | |
| 939 stack instead of the stack of all statements that were active at | |
| 940 the point of the error. | |

943 |
| 8737 | 944 Octave now includes OOP features and the user can create their own |
| 945 class objects and overloaded functions and operators. For | |
| 946 example, all methods of a class called "myclass" will be found in | |
| 947 a directory "@myclass" on the users path. The class specific | |
| 948 versions of functions and operators take precedence over the | |
| 949 generic versions of these functions. | |
| 950 | |
| 951 New functions related to OOP include | |
| 7189 | 952 |
| 8737 | 953 class inferiorto isobject loadobj methods superiorto |
| 954 | |
| 955 See the Octave manual for more details. | |
| 7038 | 956 |
| 8747 | 957 ** Parsing of Command-style Functions. |
| 958 | |
| 959 Octave now parses command-style functions without needing to first | |
| 960 declare them with "mark_as_command". The rules for recognizing a | |
| 961 command-style function calls are | |
| 962 | |
| 963 * A command must appear as the first word in a statement, | |
| 964 followed by a space. | |
| 965 | |
| 966 * The first character after the space must not be '=' or '(' | |
| 967 | |
| 968 * The next token after the space must not look like a binary | |
| 969 operator. | |
| 970 | |
| 971 These rules should be mostly compatible with the way Matlab parses | |
| 972 command-style function calls and allow users to define commands in | |
| 973 .m files without having to mark them as commands. | |
| 974 | |
| 975 Note that previous versions of Octave allowed expressions like | |
| 976 | |
| 977 x = load -text foo.dat | |
| 978 | |
| 979 but an expression like this will now generate a parse error. In | |
| 980 order to assign the value returned by a function to a variable, | |
| 981 you must use the normal function call syntax: | |
| 982 | |
| 983 x = load ("-text", "foo.dat"); | |
| 984 | |
| 8737 | 985 ** Block comments. |
| 986 | |
| 8747 | 987 Commented code can be between matching "#{" and "#}" or "%{" and |
| 988 "%}" markers, even if the commented code spans several line. This | |
| 989 allows blocks code to be commented, without needing to comment | |
| 990 each line. For example, | |
| 5814 | 991 |
| 8747 | 992 function [s, t] = func (x, y) |
| 993 s = 2 * x; | |
| 994 #{ | |
| 995 s *= y; | |
| 996 t = y + x; | |
| 997 #} | |

1053 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 1054 both time and memory consumption. |

| 1087 * logical operations | |
| 1088 * comparison operators | |
| 1089 * element-wise power | |
| 1090 * accumarray | |

| 8737 | 1099 ** 64-bit integer arithmetic. |
| 1100 | |
| 1101 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1102 supported, with saturation semantics like the other integer types. | |
| 1103 Performance of most integer arithmetic operations has been | |
| 1104 improved by using integer arithmetic directly. Previously, Octave | |
| 1105 performed integer math with saturation semantics by converting the | |
| 1106 operands to double precision, performing the operation, and then | |
| 1107 converting the result back to an integer value, truncating if | |
| 1108 necessary. | |
| 1109 | |
| 8885 | 1110 ** Diagonal and permutation matrices. |
| 1111 | |
| 1112 The interpreter can now treat diagonal and permutation matrices as | |
| 1113 special objects that store only the non-zero elements, rather than | |
| 1114 general full matrices. Therefore, it is now possible to construct | |
| 1115 and use these matrices in linear algebra without suffering a | |
| 1116 performance penalty due to storing large numbers of zero elements. | |
| 1117 | |
| 1118 ** Improvements to fsolve. | |
| 1119 | |
| 1120 The fsolve function now accepts an option structure argument (see | |
| 1121 also the optimset function). The INFO values returned from fsolve | |
| 1122 have changed to be compatible with Matlab's fsolve function. | |
| 1123 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1124 complex-differentiable complex systems, systems with a sparse | |
| 1125 jacobian and can work in single precision if given single precision | |

| 8885 | 1127 |
| 8737 | 1128 ** Improvements to the norm function. |
| 1129 | |
| 1130 The norm function is now able to compute row or column norms of a | |
| 1131 matrix in a single call, as well as general matrix p-norms. | |
| 1132 | |
| 1133 ** New functions for computing some eigenvalues or singular values. | |
| 1134 | |
| 1135 The eigs and svds functions have been included in Octave. These | |
| 1136 functions require the ARPACK library (now distributed under a | |
| 1137 GPL-compatible license). | |
| 1138 | |
| 1139 ** New QR and Cholesky factorization updating functions. | |

| 8885 | 1180 ** Changes to strcat. |
| 1181 | |
| 1182 The strcat function is now compatible with Matlab's strcat | |
| 1183 function, which removes trailing whitespace when concatenating | |
| 1184 character strings. For example | |
| 1185 | |
| 1186 strcat ('foo ', 'bar') | |
| 1187 ==> 'foobar' | |
| 1188 | |
| 1189 The new function cstrcat provides the previous behavior of | |
| 1190 Octave's strcat. | |

1194 The help system has been mostly re-implemented in .m files to make |
| 8885 | 1195 it easier to modify. Performance of the lookfor function has been |
| 1196 greatly improved by caching the help text from all functions that | |
| 1197 are distributed with Octave. The pkg function has been modified | |
| 1198 to generate cache files for external packages when they are | |
| 1199 installed. | |
