| 10118 | 521 ** The `lookup' function was extended to be more useful for |
| 522 general-purpose binary searching. Using this improvement, the | |
| 523 ismember function was rewritten for significantly better | |
| 524 performance. | |
| 9352 | 525 |
| 526 ** Real, integer and logical matrices, when used in indexing, will now | |
| 527 cache the internal index_vector value (zero-based indices) when | |
| 528 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 529 subsequent indexing by the same matrix. In particular, this means it |
| 530 is no longer needed to avoid repeated indexing by logical arrays | |
| 531 using find for performance reasons. | |
| 9888 | 532 |
| 10118 | 533 ** Logical matrices are now treated more efficiently when used as |
| 534 indices. Octave will keep the index as a logical mask unless the | |
| 535 ratio of true elements is small enough, using a specialized | |
| 536 code. Previously, all logical matrices were always first converted | |
| 537 to index vectors. This results in savings in both memory and | |
| 538 computing time. | |
| 9480 | 539 |
| 10118 | 540 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 541 functions for better performance. These functions are now faster, | |
| 542 can deliver more economized results for ranges, and can reuse the | |
| 543 index cache mechanism described in previous paragraph. | |
| 544 | |
| 545 ** The built-in function equivalents to associative operators (`plus', | |
| 546 `times', `mtimes', `and', and `or') have been extended to accept | |
| 547 multiple arguments. This is especially useful for summing | |
| 548 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 549 |
| 9449 | 550 matrix_sum = plus (matrix_list{:}); |
| 551 | |
| 10118 | 552 ** An FTP object type based on libcurl has been implemented. These |
| 553 objects allow ftp connections, downloads and uploads to be | |
| 554 managed. For example, | |
| 9880 | 555 |
| 10118 | 556 fp = ftp ("ftp.octave.org); |
| 557 cd (fp, "gnu/octave"); | |
| 558 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 559 close (fp); | |
| 9880 | 560 |
| 10118 | 561 ** The default behavior of `assert (observed, expected)' has been |
| 562 relaxed to employ less strict checking that does not require the | |
| 563 internals of the values to match. This avoids previously valid | |
| 564 tests from breaking due to new internal classes introduced in future | |
| 565 Octave versions. | |
| 9449 | 566 |
| 567 For instance, all of these assertions were true in Octave 3.0.x | |
| 568 but false in 3.2.x due to new optimizations and improvements: | |
| 569 | |
| 570 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 571 assert (zeros (0, 0), []) | |
| 572 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 573 |
| 10118 | 574 ** The behavior of library functions `ismatrix', `issquare', and |
| 575 `issymmetric' has been changed for better consistency. | |
| 9873 | 576 |
| 10292 | 577 * The `ismatrix' function now returns true for all numeric, |

578 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 579 returned false if the first or second dimension was zero. |
| 580 Hence, `ismatrix ([])' was false, | |
| 581 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 582 |
| 10118 | 583 * The `issquare' function now returns a logical scalar, and is |
| 584 equivalent to the expression | |
| 585 | |
| 586 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 587 | |
| 588 The dimension is no longer returned. As a result, `issquare ([])' | |
| 589 now yields true. | |
| 9873 | 590 |
| 10118 | 591 * The `issymmetric' function now checks for symmetry instead of |

592 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 593 logical scalar is returned rather than the dimension, so |
| 594 `issymmetric ([])' is now true. | |
| 9873 | 595 |
| 10118 | 596 ** Function handles are now aware of overloaded functions. If a |
| 597 function is overloaded, the handle determines at the time of its | |
| 598 reference which function to call. A non-overloaded version does not | |
| 599 need to exist. | |
| 9873 | 600 |
| 10118 | 601 ** Overloading functions for built-in classes (double, int8, cell, |
| 602 etc.) is now compatible with Matlab. | |
| 9408 | 603 |
| 10323 | 604 ** Function handles can now be compared with the == and != operators, |
| 605 as well as the `isequal' function. | |
| 606 | |
| 10118 | 607 ** Performance of concatenation (using []) and the functions `cat', |
| 608 `horzcat', and `vertcat' has been improved for multidimensional | |
| 609 arrays. | |
| 10117 | 610 |
| 9547 | 611 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 612 efficiently in certain cases. For instance, if M is a matrix and S a |
| 613 scalar, then the statement | |
| 9547 | 614 |
| 10118 | 615 M += S; |
| 9547 | 616 |
| 10118 | 617 will operate on M's data in-place if it is not shared by another |
| 618 variable, usually increasing both time and memory efficiency. | |
| 9547 | 619 |
| 9558 | 620 Only selected common combinations are affected, namely: |
| 9547 | 621 |
| 622 matrix += matrix | |
| 623 matrix -= matrix | |
| 9558 | 624 matrix .*= matrix |
| 625 matrix ./= matrix | |
| 626 | |
| 9547 | 627 matrix += scalar |
| 628 matrix -= scalar | |
| 629 matrix *= scalar | |
| 630 matrix /= scalar | |
| 9558 | 631 |
| 9552 | 632 logical matrix |= logical matrix |
| 633 logical matrix &= logical matrix | |
| 9547 | 634 |
| 10118 | 635 where matrix and scalar belong to the same class. The left-hand |
| 636 side must be a simple variable reference. | |
| 9888 | 637 |
| 10118 | 638 Moreover, when unary operators occur in expressions, Octave will |
| 639 also try to do the operation in-place if it's argument is a | |

640 temporary expression. |
| 9589 | 641 |
| 10118 | 642 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 643 complex numbers has changed to be consistent with the strict | |
| 644 ordering defined by the `max', `min', and `sort' functions. More | |
| 645 specifically, complex numbers are compared by lexicographical | |
| 646 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 647 parts were compared; this can be trivially achieved by converting |
| 648 the operands to real values with the `real' function. | |
| 9547 | 649 |
| 10118 | 650 ** The automatic simplification of complex computation results has |
| 651 changed. Octave will now simplify any complex number with a zero | |
| 652 imaginary part or any complex matrix with all elements having zero | |
| 653 imaginary part to a real value. Previously, this was done only for | |
| 654 positive zeros. Note that the behavior of the complex function is | |
| 655 unchanged and it still produces a complex value even if the | |
| 656 imaginary part is zero. | |
| 9826 | 657 |
| 10118 | 658 ** As a side effect of code refactoring in liboctave, the binary |
| 659 logical operations are now more easily amenable to compiler | |
| 660 optimizations and are thus significantly faster. | |
| 9595 | 661 |
| 10118 | 662 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 663 redundant copies. For more information, see the manual. | |

670 V / M |
| 9664 | 671 |
| 10118 | 672 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 673 In particular, if M is triangular, all three expressions will be | |
| 674 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 675 flags. Previously, all three expressions required a physical |
| 10118 | 676 transpose of M. |
| 9664 | 677 |
| 10118 | 678 ** More efficient handling of certain mixed real-complex matrix |
| 679 operations. For instance, if RM is a real matrix and CM a complex | |
| 680 matrix, | |
| 9664 | 681 |
| 10118 | 682 RM * CM |
| 9664 | 683 |
| 684 can now be evaluated either as | |
| 685 | |
| 686 complex (RM * real (CM), RM * imag (CM)) | |
| 687 | |
| 688 or as | |
| 689 | |
| 690 complex (RM) * CM, | |
| 691 | |
| 10453 | 692 depending on the dimensions. The first form requires more |
| 693 temporaries and copying, but halves the FLOP count, which normally | |
| 694 brings better performance if RM has enough rows. Previously, the | |
| 695 second form was always used. | |
| 9664 | 696 |
| 11111 | 697 Matrix division is similarly affected. |
| 9664 | 698 |
| 10118 | 699 ** More efficient handling of triangular matrix factors returned from |
| 700 factorizations. The functions for computing QR, LU and Cholesky | |
| 701 factorizations will now automatically return the triangular matrix | |
| 702 factors with proper internal matrix_type set, so that it won't need | |
| 703 to be computed when the matrix is used for division. | |
| 9717 | 704 |
| 10118 | 705 ** The built-in `sum' function now handles the non-native summation |
| 706 (i.e., double precision sum of single or integer inputs) more | |
| 707 efficiently, avoiding a temporary conversion of the whole input | |
| 708 array to doubles. Further, `sum' can now accept an extra option | |
| 709 argument, using a compensated summation algorithm rather than a | |
| 710 straightforward sum, which significantly improves precision if lots | |
| 711 of cancellation occurs in the summation. | |
| 9717 | 712 |
| 10118 | 713 ** The built-in `bsxfun' function now uses optimized code for certain |
| 714 cases where built-in operator handles are passed in. Namely, the | |
| 715 optimizations concern the operators `plus', `minus', `times', | |
| 716 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 717 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 718 functions `min' and `max'. Optimizations only apply when both | |
| 719 operands are of the same built-in class. Mixed real/complex and | |
| 720 single/double operations will first convert both operands to a | |
| 721 common type. | |
| 9745 | 722 |
| 10118 | 723 ** The `strfind' and `strrep' functions now have compiled |
| 724 implementations, facilitating significantly more efficient searching | |
| 725 and replacing in strings, especially with longer patterns. The code | |
| 726 of `strcat' has been vectorized and is now much more efficient when | |
| 727 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 728 functions are now built-in functions, providing better performance. | |

| 738 For more details, consult the manual. | |

| 750 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |

| 10453 | 753 ** rem and mod are now built-in functions. They also handle integer |
| 754 types efficiently using integer arithmetic. | |
| 10437 | 755 |
| 10536 | 756 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 757 Since Octave uses compressed column storage for sparse matrices, | |
| 758 major attention is devoted to operations manipulating whole columns. | |
| 759 Such operations are now significantly faster, as well as some other | |
| 760 important cases. | |
| 761 | |
| 762 Further, it is now possible to pre-allocate a sparse matrix and | |
| 763 subsequently fill it by assignments, provided they meet certain | |
| 764 conditions. For more information, consult the `spalloc' function, | |
| 765 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 766 longer always equal in Octave. Octave may also produce a matrix |
| 767 with nnz < nzmax as a result of other operations, so you should | |

768 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 769 space allocated for nonzero elements). |
| 10536 | 770 |
| 771 Sparse concatenation is also affected, and concatenating sparse | |
| 772 matrices, especially larger collections, is now significantly more | |
| 11111 | 773 efficient. This applies to both the [] operator and the |
| 10536 | 774 cat/vertcat/horzcat functions. |
| 775 | |
| 11111 | 776 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 777 for computing the singular value decomposition using svd, instead |
| 11111 | 778 of the default xGESVD, using the configuration pseudo-variable |
| 779 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 780 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 781 robust on highly ill-conditioned matrices. |
| 782 | |
| 783 ** Configuration pseudo-variables, such as page_screen_output or | |
| 784 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |

999 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 1000 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 1001 removed from Octave. These function were incompatible with the | |
| 1002 high level graphics handle code. | |
| 6329 | 1003 |
| 8885 | 1004 ** The Control, Finance and Quaternion functions have been removed. |
| 1005 | |
| 1006 These functions are now available as separate packages from | |
| 1007 | |
| 1008 http://octave.sourceforge.net/packages.html | |
| 1009 | |
| 1010 and can be reinstalled using the Octave package manager (see | |
| 1011 the pkg function). | |
| 1012 | |
| 1013 ** Specific sparse matrix functions removed. | |
| 1014 | |
| 1015 The following functions, which handled only sparse matrices have | |
| 1016 been removed. Instead of calling these functions directly, you | |
| 1017 should use the corresponding function without the "sp" prefix. | |
| 8737 | 1018 |

| 1020 spchol spdet splchol spqr | |

| 1023 spcumprod spinv spmin | |
| 1024 | |
| 1025 ** Improvements to the debugger. | |
| 1026 | |
| 1027 The interactive debugging features have been improved. Stopping | |
| 1028 on statements with dbstop should work correctly now. Stepping | |
| 1029 into and over functions, and stepping one statement at a time | |
| 1030 (with dbstep) now works. Moving up and down the call stack with | |
| 1031 dbup and dbdown now works. The dbstack function is now available | |
| 1032 to print the current function call stack. The new dbquit function | |
| 1033 is available to exit the debugging mode. | |
| 1034 | |
| 1035 ** Improved traceback error messages. | |
| 1036 | |
| 1037 Traceback error messages are much more concise and easier to | |
| 1038 understand. They now display information about the function call | |
| 1039 stack instead of the stack of all statements that were active at | |
| 1040 the point of the error. | |

1043 |
| 8737 | 1044 Octave now includes OOP features and the user can create their own |
| 1045 class objects and overloaded functions and operators. For | |
| 1046 example, all methods of a class called "myclass" will be found in | |
| 1047 a directory "@myclass" on the users path. The class specific | |
| 1048 versions of functions and operators take precedence over the | |
| 1049 generic versions of these functions. | |
| 1050 | |
| 1051 New functions related to OOP include | |
| 7189 | 1052 |
| 8737 | 1053 class inferiorto isobject loadobj methods superiorto |
| 1054 | |
| 1055 See the Octave manual for more details. | |
| 7038 | 1056 |
| 8747 | 1057 ** Parsing of Command-style Functions. |
| 1058 | |
| 1059 Octave now parses command-style functions without needing to first | |
| 1060 declare them with "mark_as_command". The rules for recognizing a | |
| 1061 command-style function calls are | |
| 1062 | |
| 1063 * A command must appear as the first word in a statement, | |
| 1064 followed by a space. | |
| 1065 | |
| 1066 * The first character after the space must not be '=' or '(' | |
| 1067 | |
| 1068 * The next token after the space must not look like a binary | |
| 1069 operator. | |
| 1070 | |
| 1071 These rules should be mostly compatible with the way Matlab parses | |
| 1072 command-style function calls and allow users to define commands in | |
| 1073 .m files without having to mark them as commands. | |
| 1074 | |
| 1075 Note that previous versions of Octave allowed expressions like | |
| 1076 | |
| 1077 x = load -text foo.dat | |
| 1078 | |
| 1079 but an expression like this will now generate a parse error. In | |
| 1080 order to assign the value returned by a function to a variable, | |
| 1081 you must use the normal function call syntax: | |
| 1082 | |
| 1083 x = load ("-text", "foo.dat"); | |
| 1084 | |
| 8737 | 1085 ** Block comments. |
| 1086 | |
| 8747 | 1087 Commented code can be between matching "#{" and "#}" or "%{" and |
| 1088 "%}" markers, even if the commented code spans several line. This | |
| 1089 allows blocks code to be commented, without needing to comment | |
| 1090 each line. For example, | |
| 5814 | 1091 |
| 8747 | 1092 function [s, t] = func (x, y) |
| 1093 s = 2 * x; | |
| 1094 #{ | |
| 1095 s *= y; | |
| 1096 t = y + x; | |
| 1097 #} | |

1153 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 1154 both time and memory consumption. |
| 9128 | 1155 Also, Octave will now attempt to detect and optimize usage of a vector |

| 9006 | 1186 |
| 1187 * logical operations | |
| 1188 * comparison operators | |
| 1189 * element-wise power | |
| 1190 * accumarray | |
| 1191 * cellfun | |
| 1192 * isnan | |
| 1193 * isinf | |
| 1194 * isfinite | |

| 1196 * repmat | |
| 1197 * strcmp | |
| 1198 | |
| 8737 | 1199 ** 64-bit integer arithmetic. |
| 1200 | |
| 1201 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1202 supported, with saturation semantics like the other integer types. | |
| 1203 Performance of most integer arithmetic operations has been | |
| 1204 improved by using integer arithmetic directly. Previously, Octave | |
| 1205 performed integer math with saturation semantics by converting the | |
| 1206 operands to double precision, performing the operation, and then | |
| 1207 converting the result back to an integer value, truncating if | |
| 1208 necessary. | |
| 1209 | |
| 8885 | 1210 ** Diagonal and permutation matrices. |
| 1211 | |
| 1212 The interpreter can now treat diagonal and permutation matrices as | |
| 1213 special objects that store only the non-zero elements, rather than | |
| 1214 general full matrices. Therefore, it is now possible to construct | |
| 1215 and use these matrices in linear algebra without suffering a | |
| 1216 performance penalty due to storing large numbers of zero elements. | |
| 1217 | |
| 1218 ** Improvements to fsolve. | |
| 1219 | |
| 1220 The fsolve function now accepts an option structure argument (see | |
| 1221 also the optimset function). The INFO values returned from fsolve | |
| 1222 have changed to be compatible with Matlab's fsolve function. | |
| 1223 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1224 complex-differentiable complex systems, systems with a sparse | |
| 1225 jacobian and can work in single precision if given single precision | |

| 8885 | 1227 |
| 8737 | 1228 ** Improvements to the norm function. |
| 1229 | |
| 1230 The norm function is now able to compute row or column norms of a | |
| 1231 matrix in a single call, as well as general matrix p-norms. | |
| 1232 | |
| 1233 ** New functions for computing some eigenvalues or singular values. | |
| 1234 | |
| 1235 The eigs and svds functions have been included in Octave. These | |
| 1236 functions require the ARPACK library (now distributed under a | |
| 1237 GPL-compatible license). | |
| 1238 | |
| 1239 ** New QR and Cholesky factorization updating functions. | |

| 8885 | 1280 ** Changes to strcat. |
| 1281 | |
| 1282 The strcat function is now compatible with Matlab's strcat | |
| 1283 function, which removes trailing whitespace when concatenating | |
| 1284 character strings. For example | |
| 1285 | |
| 1286 strcat ('foo ', 'bar') | |
| 1287 ==> 'foobar' | |
| 1288 | |
| 1289 The new function cstrcat provides the previous behavior of | |
| 1290 Octave's strcat. | |

1294 The help system has been mostly re-implemented in .m files to make |
| 8885 | 1295 it easier to modify. Performance of the lookfor function has been |
| 1296 greatly improved by caching the help text from all functions that | |
| 1297 are distributed with Octave. The pkg function has been modified | |
| 1298 to generate cache files for external packages when they are | |
| 1299 installed. | |
