| 10118 | 470 ** The `lookup' function was extended to be more useful for |
| 471 general-purpose binary searching. Using this improvement, the | |
| 472 ismember function was rewritten for significantly better | |
| 473 performance. | |
| 9352 | 474 |
| 475 ** Real, integer and logical matrices, when used in indexing, will now | |
| 476 cache the internal index_vector value (zero-based indices) when | |
| 477 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 478 subsequent indexing by the same matrix. In particular, this means it |
| 479 is no longer needed to avoid repeated indexing by logical arrays | |
| 480 using find for performance reasons. | |
| 9888 | 481 |
| 10118 | 482 ** Logical matrices are now treated more efficiently when used as |
| 483 indices. Octave will keep the index as a logical mask unless the | |
| 484 ratio of true elements is small enough, using a specialized | |
| 485 code. Previously, all logical matrices were always first converted | |
| 486 to index vectors. This results in savings in both memory and | |
| 487 computing time. | |
| 9480 | 488 |
| 10118 | 489 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 490 functions for better performance. These functions are now faster, | |
| 491 can deliver more economized results for ranges, and can reuse the | |
| 492 index cache mechanism described in previous paragraph. | |
| 493 | |
| 494 ** The built-in function equivalents to associative operators (`plus', | |
| 495 `times', `mtimes', `and', and `or') have been extended to accept | |
| 496 multiple arguments. This is especially useful for summing | |
| 497 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 498 |
| 9449 | 499 matrix_sum = plus (matrix_list{:}); |
| 500 | |
| 10118 | 501 ** An FTP object type based on libcurl has been implemented. These |
| 502 objects allow ftp connections, downloads and uploads to be | |
| 503 managed. For example, | |
| 9880 | 504 |
| 10118 | 505 fp = ftp ("ftp.octave.org); |
| 506 cd (fp, "gnu/octave"); | |
| 507 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 508 close (fp); | |
| 9880 | 509 |
| 10118 | 510 ** The default behavior of `assert (observed, expected)' has been |
| 511 relaxed to employ less strict checking that does not require the | |
| 512 internals of the values to match. This avoids previously valid | |
| 513 tests from breaking due to new internal classes introduced in future | |
| 514 Octave versions. | |
| 9449 | 515 |
| 516 For instance, all of these assertions were true in Octave 3.0.x | |
| 517 but false in 3.2.x due to new optimizations and improvements: | |
| 518 | |
| 519 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 520 assert (zeros (0, 0), []) | |
| 521 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 522 |
| 10118 | 523 ** The behavior of library functions `ismatrix', `issquare', and |
| 524 `issymmetric' has been changed for better consistency. | |
| 9873 | 525 |
| 10292 | 526 * The `ismatrix' function now returns true for all numeric, |

527 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 528 returned false if the first or second dimension was zero. |
| 529 Hence, `ismatrix ([])' was false, | |
| 530 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 531 |
| 10118 | 532 * The `issquare' function now returns a logical scalar, and is |
| 533 equivalent to the expression | |
| 534 | |
| 535 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 536 | |
| 537 The dimension is no longer returned. As a result, `issquare ([])' | |
| 538 now yields true. | |
| 9873 | 539 |
| 10118 | 540 * The `issymmetric' function now checks for symmetry instead of |

541 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 542 logical scalar is returned rather than the dimension, so |
| 543 `issymmetric ([])' is now true. | |
| 9873 | 544 |
| 10118 | 545 ** Function handles are now aware of overloaded functions. If a |
| 546 function is overloaded, the handle determines at the time of its | |
| 547 reference which function to call. A non-overloaded version does not | |
| 548 need to exist. | |
| 9873 | 549 |
| 10118 | 550 ** Overloading functions for built-in classes (double, int8, cell, |
| 551 etc.) is now compatible with Matlab. | |
| 9408 | 552 |
| 10323 | 553 ** Function handles can now be compared with the == and != operators, |
| 554 as well as the `isequal' function. | |
| 555 | |
| 10118 | 556 ** Performance of concatenation (using []) and the functions `cat', |
| 557 `horzcat', and `vertcat' has been improved for multidimensional | |
| 558 arrays. | |
| 10117 | 559 |
| 9547 | 560 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 561 efficiently in certain cases. For instance, if M is a matrix and S a |
| 562 scalar, then the statement | |
| 9547 | 563 |
| 10118 | 564 M += S; |
| 9547 | 565 |
| 10118 | 566 will operate on M's data in-place if it is not shared by another |
| 567 variable, usually increasing both time and memory efficiency. | |
| 9547 | 568 |
| 9558 | 569 Only selected common combinations are affected, namely: |
| 9547 | 570 |
| 571 matrix += matrix | |
| 572 matrix -= matrix | |
| 9558 | 573 matrix .*= matrix |
| 574 matrix ./= matrix | |
| 575 | |
| 9547 | 576 matrix += scalar |
| 577 matrix -= scalar | |
| 578 matrix *= scalar | |
| 579 matrix /= scalar | |
| 9558 | 580 |
| 9552 | 581 logical matrix |= logical matrix |
| 582 logical matrix &= logical matrix | |
| 9547 | 583 |
| 10118 | 584 where matrix and scalar belong to the same class. The left-hand |
| 585 side must be a simple variable reference. | |
| 9888 | 586 |
| 10118 | 587 Moreover, when unary operators occur in expressions, Octave will |
| 588 also try to do the operation in-place if it's argument is a | |

589 temporary expression. |
| 9589 | 590 |
| 10118 | 591 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 592 complex numbers has changed to be consistent with the strict | |
| 593 ordering defined by the `max', `min', and `sort' functions. More | |
| 594 specifically, complex numbers are compared by lexicographical | |
| 595 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 596 parts were compared; this can be trivially achieved by converting |
| 597 the operands to real values with the `real' function. | |
| 9547 | 598 |
| 10118 | 599 ** The automatic simplification of complex computation results has |
| 600 changed. Octave will now simplify any complex number with a zero | |
| 601 imaginary part or any complex matrix with all elements having zero | |
| 602 imaginary part to a real value. Previously, this was done only for | |
| 603 positive zeros. Note that the behavior of the complex function is | |
| 604 unchanged and it still produces a complex value even if the | |
| 605 imaginary part is zero. | |
| 9826 | 606 |
| 10118 | 607 ** As a side effect of code refactoring in liboctave, the binary |
| 608 logical operations are now more easily amenable to compiler | |
| 609 optimizations and are thus significantly faster. | |
| 9595 | 610 |
| 10118 | 611 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 612 redundant copies. For more information, see the manual. | |

| 10118 | 615 handle the expressions |

619 V / M |
| 9664 | 620 |
| 10118 | 621 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 622 In particular, if M is triangular, all three expressions will be | |
| 623 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 624 flags. Previously, all three expressions required a physical |
| 10118 | 625 transpose of M. |
| 9664 | 626 |
| 10118 | 627 ** More efficient handling of certain mixed real-complex matrix |
| 628 operations. For instance, if RM is a real matrix and CM a complex | |
| 629 matrix, | |
| 9664 | 630 |
| 10118 | 631 RM * CM |
| 9664 | 632 |
| 633 can now be evaluated either as | |
| 634 | |
| 635 complex (RM * real (CM), RM * imag (CM)) | |
| 636 | |
| 637 or as | |
| 638 | |
| 639 complex (RM) * CM, | |
| 640 | |
| 10453 | 641 depending on the dimensions. The first form requires more |
| 642 temporaries and copying, but halves the FLOP count, which normally | |
| 643 brings better performance if RM has enough rows. Previously, the | |
| 644 second form was always used. | |
| 9664 | 645 |
| 11111 | 646 Matrix division is similarly affected. |
| 9664 | 647 |
| 10118 | 648 ** More efficient handling of triangular matrix factors returned from |
| 649 factorizations. The functions for computing QR, LU and Cholesky | |
| 650 factorizations will now automatically return the triangular matrix | |
| 651 factors with proper internal matrix_type set, so that it won't need | |
| 652 to be computed when the matrix is used for division. | |
| 9717 | 653 |
| 10118 | 654 ** The built-in `sum' function now handles the non-native summation |
| 655 (i.e., double precision sum of single or integer inputs) more | |
| 656 efficiently, avoiding a temporary conversion of the whole input | |
| 657 array to doubles. Further, `sum' can now accept an extra option | |
| 658 argument, using a compensated summation algorithm rather than a | |
| 659 straightforward sum, which significantly improves precision if lots | |

| 9717 | 661 |
| 10118 | 662 ** The built-in `bsxfun' function now uses optimized code for certain |
| 663 cases where built-in operator handles are passed in. Namely, the | |
| 664 optimizations concern the operators `plus', `minus', `times', | |
| 665 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 666 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 667 functions `min' and `max'. Optimizations only apply when both | |
| 668 operands are of the same built-in class. Mixed real/complex and | |
| 669 single/double operations will first convert both operands to a | |
| 670 common type. | |
| 9745 | 671 |
| 10118 | 672 ** The `strfind' and `strrep' functions now have compiled |
| 673 implementations, facilitating significantly more efficient searching | |
| 674 and replacing in strings, especially with longer patterns. The code | |
| 675 of `strcat' has been vectorized and is now much more efficient when | |
| 676 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 677 functions are now built-in functions, providing better performance. | |

| 11111 | 685 tilde (~) is now supported. Ignored output arguments may be |
| 686 detected from a function using the built-in function `isargout'. | |
| 687 For more details, consult the manual. | |
| 10886 | 688 |
| 10453 | 689 ** The list datatype, deprecated since the introduction of cells, has |
| 690 been removed. | |

| 696 Matlab-compatible. | |

| 699 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 700 Octave:int-math-overflow) have been removed. |

| 10453 | 702 ** rem and mod are now built-in functions. They also handle integer |
| 703 types efficiently using integer arithmetic. | |
| 10437 | 704 |
| 10536 | 705 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 706 Since Octave uses compressed column storage for sparse matrices, | |
| 707 major attention is devoted to operations manipulating whole columns. | |
| 708 Such operations are now significantly faster, as well as some other | |
| 709 important cases. | |
| 710 | |
| 711 Further, it is now possible to pre-allocate a sparse matrix and | |
| 712 subsequently fill it by assignments, provided they meet certain | |
| 713 conditions. For more information, consult the `spalloc' function, | |
| 714 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 715 longer always equal in Octave. Octave may also produce a matrix |
| 716 with nnz < nzmax as a result of other operations, so you should | |

717 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 718 space allocated for nonzero elements). |
| 10536 | 719 |
| 720 Sparse concatenation is also affected, and concatenating sparse | |
| 721 matrices, especially larger collections, is now significantly more | |
| 11111 | 722 efficient. This applies to both the [] operator and the |
| 10536 | 723 cat/vertcat/horzcat functions. |
| 724 | |
| 11111 | 725 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 726 for computing the singular value decomposition using svd, instead |
| 11111 | 727 of the default xGESVD, using the configuration pseudo-variable |
| 728 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 729 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 730 robust on highly ill-conditioned matrices. |
| 731 | |
| 732 ** Configuration pseudo-variables, such as page_screen_output or | |
| 733 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |

948 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 949 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 950 removed from Octave. These function were incompatible with the | |
| 951 high level graphics handle code. | |
| 6329 | 952 |
| 8885 | 953 ** The Control, Finance and Quaternion functions have been removed. |
| 954 | |
| 955 These functions are now available as separate packages from | |
| 956 | |
| 957 http://octave.sourceforge.net/packages.html | |
| 958 | |
| 959 and can be reinstalled using the Octave package manager (see | |
| 960 the pkg function). | |
| 961 | |
| 962 ** Specific sparse matrix functions removed. | |
| 963 | |
| 964 The following functions, which handled only sparse matrices have | |
| 965 been removed. Instead of calling these functions directly, you | |
| 966 should use the corresponding function without the "sp" prefix. | |

| 972 spcumprod spinv spmin | |
| 973 | |
| 974 ** Improvements to the debugger. | |
| 975 | |
| 976 The interactive debugging features have been improved. Stopping | |
| 977 on statements with dbstop should work correctly now. Stepping | |
| 978 into and over functions, and stepping one statement at a time | |
| 979 (with dbstep) now works. Moving up and down the call stack with | |
| 980 dbup and dbdown now works. The dbstack function is now available | |
| 981 to print the current function call stack. The new dbquit function | |
| 982 is available to exit the debugging mode. | |
| 983 | |
| 984 ** Improved traceback error messages. | |
| 985 | |
| 986 Traceback error messages are much more concise and easier to | |
| 987 understand. They now display information about the function call | |
| 988 stack instead of the stack of all statements that were active at | |
| 989 the point of the error. | |

| 997 versions of functions and operators take precedence over the | |
| 998 generic versions of these functions. | |

| 7038 | 1005 |
| 8747 | 1006 ** Parsing of Command-style Functions. |
| 1007 | |
| 1008 Octave now parses command-style functions without needing to first | |
| 1009 declare them with "mark_as_command". The rules for recognizing a | |
| 1010 command-style function calls are | |
| 1011 | |
| 1012 * A command must appear as the first word in a statement, | |
| 1013 followed by a space. | |
| 1014 | |
| 1015 * The first character after the space must not be '=' or '(' | |
| 1016 | |
| 1017 * The next token after the space must not look like a binary | |
| 1018 operator. | |
| 1019 | |
| 1020 These rules should be mostly compatible with the way Matlab parses | |
| 1021 command-style function calls and allow users to define commands in | |
| 1022 .m files without having to mark them as commands. | |
| 1023 | |
| 1024 Note that previous versions of Octave allowed expressions like | |
| 1025 | |
| 1026 x = load -text foo.dat | |
| 1027 | |
| 1028 but an expression like this will now generate a parse error. In | |
| 1029 order to assign the value returned by a function to a variable, | |
| 1030 you must use the normal function call syntax: | |
| 1031 | |
| 1032 x = load ("-text", "foo.dat"); | |
| 1033 | |
| 8737 | 1034 ** Block comments. |
| 1035 | |
| 8747 | 1036 Commented code can be between matching "#{" and "#}" or "%{" and |
| 1037 "%}" markers, even if the commented code spans several line. This | |
| 1038 allows blocks code to be commented, without needing to comment | |
| 1039 each line. For example, | |
| 5814 | 1040 |
| 8747 | 1041 function [s, t] = func (x, y) |
| 1042 s = 2 * x; | |
| 1043 #{ | |
| 1044 s *= y; | |
| 1045 t = y + x; | |
| 1046 #} | |

1102 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 1103 both time and memory consumption. |

| 1105 as a stack, when elements are being repeatedly inserted at/removed from | |
| 1106 the end of the vector. | |

1127 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 1128 increment are allowed and can be constructed using the built-in |
| 1129 function `ones'. | |
| 9006 | 1130 |
| 1131 ** Various performance improvements. | |
| 1132 | |
| 10453 | 1133 Performance of a number of other built-in operations and functions |
| 1134 was improved, including: | |
| 9006 | 1135 |
| 1136 * logical operations | |
| 1137 * comparison operators | |
| 1138 * element-wise power | |
| 1139 * accumarray | |
| 1140 * cellfun | |
| 1141 * isnan | |
| 1142 * isinf | |
| 1143 * isfinite | |
| 1144 * nchoosek | |
| 1145 * repmat | |
| 1146 * strcmp | |
| 1147 | |
| 8737 | 1148 ** 64-bit integer arithmetic. |
| 1149 | |
| 1150 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1151 supported, with saturation semantics like the other integer types. | |
| 1152 Performance of most integer arithmetic operations has been | |
| 1153 improved by using integer arithmetic directly. Previously, Octave | |
| 1154 performed integer math with saturation semantics by converting the | |
| 1155 operands to double precision, performing the operation, and then | |
| 1156 converting the result back to an integer value, truncating if | |
| 1157 necessary. | |
| 1158 | |
| 8885 | 1159 ** Diagonal and permutation matrices. |
| 1160 | |
| 1161 The interpreter can now treat diagonal and permutation matrices as | |
| 1162 special objects that store only the non-zero elements, rather than | |
| 1163 general full matrices. Therefore, it is now possible to construct | |
| 1164 and use these matrices in linear algebra without suffering a | |
| 1165 performance penalty due to storing large numbers of zero elements. | |
| 1166 | |
| 1167 ** Improvements to fsolve. | |
| 1168 | |
| 1169 The fsolve function now accepts an option structure argument (see | |
| 1170 also the optimset function). The INFO values returned from fsolve | |
| 1171 have changed to be compatible with Matlab's fsolve function. | |
| 1172 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1173 complex-differentiable complex systems, systems with a sparse | |
| 1174 jacobian and can work in single precision if given single precision | |

| 1182 ** New functions for computing some eigenvalues or singular values. | |
