10118 | 639 ** The `lookup' function was extended to be more useful for |
640 general-purpose binary searching. Using this improvement, the | |
641 ismember function was rewritten for significantly better | |
642 performance. | |
9352 | 643 |
644 ** Real, integer and logical matrices, when used in indexing, will now | |
645 cache the internal index_vector value (zero-based indices) when | |
646 successfully used as indices, eliminating the conversion penalty for | |
10118 | 647 subsequent indexing by the same matrix. In particular, this means it |
648 is no longer needed to avoid repeated indexing by logical arrays | |
649 using find for performance reasons. | |
9888 | 650 |
10118 | 651 ** Logical matrices are now treated more efficiently when used as |
652 indices. Octave will keep the index as a logical mask unless the | |
653 ratio of true elements is small enough, using a specialized | |
654 code. Previously, all logical matrices were always first converted | |
655 to index vectors. This results in savings in both memory and | |
656 computing time. | |
9480 | 657 |
10118 | 658 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
659 functions for better performance. These functions are now faster, | |
660 can deliver more economized results for ranges, and can reuse the | |
661 index cache mechanism described in previous paragraph. | |
662 | |
663 ** The built-in function equivalents to associative operators (`plus', | |
664 `times', `mtimes', `and', and `or') have been extended to accept | |
665 multiple arguments. This is especially useful for summing | |
666 (multiplying, etc.) lists of objects (of possibly distinct types): | |
9408 | 667 |
9449 | 668 matrix_sum = plus (matrix_list{:}); |
669 | |
10118 | 670 ** An FTP object type based on libcurl has been implemented. These |
671 objects allow ftp connections, downloads and uploads to be | |
672 managed. For example, | |
9880 | 673 |
10118 | 674 fp = ftp ("ftp.octave.org); |
675 cd (fp, "gnu/octave"); | |
676 mget (fp, "octave-3.2.3.tar.bz2"); | |
677 close (fp); | |
9880 | 678 |
10118 | 679 ** The default behavior of `assert (observed, expected)' has been |
680 relaxed to employ less strict checking that does not require the | |
681 internals of the values to match. This avoids previously valid | |
682 tests from breaking due to new internal classes introduced in future | |
683 Octave versions. | |
9449 | 684 |
685 For instance, all of these assertions were true in Octave 3.0.x | |
686 but false in 3.2.x due to new optimizations and improvements: | |
687 | |
688 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
689 assert (zeros (0, 0), []) | |
690 assert (2*ones (1, 5), (2) (ones (1,5))) | |
9462 | 691 |
10118 | 692 ** The behavior of library functions `ismatrix', `issquare', and |
693 `issymmetric' has been changed for better consistency. | |

696 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
10292 | 697 returned false if the first or second dimension was zero. |
698 Hence, `ismatrix ([])' was false, | |
699 while `ismatrix (zeros (1,2,0))' was true. | |
9873 | 700 |
10118 | 701 * The `issquare' function now returns a logical scalar, and is |
702 equivalent to the expression | |
703 | |
704 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
705 | |
706 The dimension is no longer returned. As a result, `issquare ([])' | |
707 now yields true. | |
9873 | 708 |
10118 | 709 * The `issymmetric' function now checks for symmetry instead of |

710 Hermitianness. For the latter, ishermitian was created. Also, |
10118 | 711 logical scalar is returned rather than the dimension, so |
712 `issymmetric ([])' is now true. | |
9873 | 713 |
10118 | 714 ** Function handles are now aware of overloaded functions. If a |
715 function is overloaded, the handle determines at the time of its | |
716 reference which function to call. A non-overloaded version does not | |
717 need to exist. | |
9873 | 718 |
10118 | 719 ** Overloading functions for built-in classes (double, int8, cell, |
720 etc.) is now compatible with Matlab. | |
9408 | 721 |
10323 | 722 ** Function handles can now be compared with the == and != operators, |
723 as well as the `isequal' function. | |
724 | |
10118 | 725 ** Performance of concatenation (using []) and the functions `cat', |
726 `horzcat', and `vertcat' has been improved for multidimensional | |
727 arrays. | |
10117 | 728 |
9547 | 729 ** The operation-assignment operators +=, -=, *= and /= now behave more |
10118 | 730 efficiently in certain cases. For instance, if M is a matrix and S a |
731 scalar, then the statement | |
9547 | 732 |
10118 | 733 M += S; |
9547 | 734 |
10118 | 735 will operate on M's data in-place if it is not shared by another |
736 variable, usually increasing both time and memory efficiency. | |
9547 | 737 |
9558 | 738 Only selected common combinations are affected, namely: |
9547 | 739 |
740 matrix += matrix | |
741 matrix -= matrix | |
9558 | 742 matrix .*= matrix |
743 matrix ./= matrix | |
744 | |
9547 | 745 matrix += scalar |
746 matrix -= scalar | |
747 matrix *= scalar | |
748 matrix /= scalar | |
9558 | 749 |
9552 | 750 logical matrix |= logical matrix |
751 logical matrix &= logical matrix | |
9547 | 752 |
10118 | 753 where matrix and scalar belong to the same class. The left-hand |
754 side must be a simple variable reference. | |
9888 | 755 |
10118 | 756 Moreover, when unary operators occur in expressions, Octave will |
757 also try to do the operation in-place if it's argument is a | |

758 temporary expression. |
9589 | 759 |
10118 | 760 ** The effect of comparison operators (<, >, <=, and >=) applied to |
761 complex numbers has changed to be consistent with the strict | |
762 ordering defined by the `max', `min', and `sort' functions. More | |
763 specifically, complex numbers are compared by lexicographical | |
764 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
14188 | 765 parts were compared; this can be trivially achieved by converting |
766 the operands to real values with the `real' function. | |
9547 | 767 |
10118 | 768 ** The automatic simplification of complex computation results has |
769 changed. Octave will now simplify any complex number with a zero | |
770 imaginary part or any complex matrix with all elements having zero | |
771 imaginary part to a real value. Previously, this was done only for | |
772 positive zeros. Note that the behavior of the complex function is | |
773 unchanged and it still produces a complex value even if the | |
774 imaginary part is zero. | |
9826 | 775 |
10118 | 776 ** As a side effect of code refactoring in liboctave, the binary |
777 logical operations are now more easily amenable to compiler | |
778 optimizations and are thus significantly faster. | |
9595 | 779 |
10118 | 780 ** Octave now allows user-defined `subsasgn' methods to optimize out |
781 redundant copies. For more information, see the manual. | |
9595 | 782 |
10453 | 783 ** More efficient matrix division handling. Octave is now able to |

788 V / M |
9664 | 789 |
10118 | 790 (M is a matrix and V is a vector) more efficiently in certain cases. |
791 In particular, if M is triangular, all three expressions will be | |
792 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
10453 | 793 flags. Previously, all three expressions required a physical |
10118 | 794 transpose of M. |
9664 | 795 |
10118 | 796 ** More efficient handling of certain mixed real-complex matrix |
797 operations. For instance, if RM is a real matrix and CM a complex | |
798 matrix, | |
9664 | 799 |
10118 | 800 RM * CM |
9664 | 801 |
802 can now be evaluated either as | |
803 | |
804 complex (RM * real (CM), RM * imag (CM)) | |
805 | |
806 or as | |
807 | |
808 complex (RM) * CM, | |
809 | |
10453 | 810 depending on the dimensions. The first form requires more |
811 temporaries and copying, but halves the FLOP count, which normally | |
812 brings better performance if RM has enough rows. Previously, the | |
813 second form was always used. | |
9664 | 814 |
11111 | 815 Matrix division is similarly affected. |
9664 | 816 |
10118 | 817 ** More efficient handling of triangular matrix factors returned from |
818 factorizations. The functions for computing QR, LU and Cholesky | |
819 factorizations will now automatically return the triangular matrix | |
820 factors with proper internal matrix_type set, so that it won't need | |
821 to be computed when the matrix is used for division. | |
9717 | 822 |
10118 | 823 ** The built-in `sum' function now handles the non-native summation |
824 (i.e., double precision sum of single or integer inputs) more | |
825 efficiently, avoiding a temporary conversion of the whole input | |
826 array to doubles. Further, `sum' can now accept an extra option | |
827 argument, using a compensated summation algorithm rather than a | |
828 straightforward sum, which significantly improves precision if lots | |
829 of cancellation occurs in the summation. | |
9717 | 830 |
10118 | 831 ** The built-in `bsxfun' function now uses optimized code for certain |
832 cases where built-in operator handles are passed in. Namely, the | |
833 optimizations concern the operators `plus', `minus', `times', | |
834 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
835 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
836 functions `min' and `max'. Optimizations only apply when both | |
837 operands are of the same built-in class. Mixed real/complex and | |
838 single/double operations will first convert both operands to a | |
839 common type. | |
9745 | 840 |
10118 | 841 ** The `strfind' and `strrep' functions now have compiled |
842 implementations, facilitating significantly more efficient searching | |
843 and replacing in strings, especially with longer patterns. The code | |
844 of `strcat' has been vectorized and is now much more efficient when | |
845 many strings are concatenated. The `strcmpi' and `strncmpi' | |
846 functions are now built-in functions, providing better performance. | |

10453 | 871 ** rem and mod are now built-in functions. They also handle integer |
872 types efficiently using integer arithmetic. | |
10437 | 873 |
10536 | 874 ** Sparse indexing and indexed assignment has been mostly rewritten. |
875 Since Octave uses compressed column storage for sparse matrices, | |
876 major attention is devoted to operations manipulating whole columns. | |
877 Such operations are now significantly faster, as well as some other | |
878 important cases. | |
879 | |
880 Further, it is now possible to pre-allocate a sparse matrix and | |
881 subsequently fill it by assignments, provided they meet certain | |
882 conditions. For more information, consult the `spalloc' function, | |
883 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
11111 | 884 longer always equal in Octave. Octave may also produce a matrix |
885 with nnz < nzmax as a result of other operations, so you should | |

886 consistently use nnz unless you really want to use nzmax (i.e., the |
11111 | 887 space allocated for nonzero elements). |
10536 | 888 |
889 Sparse concatenation is also affected, and concatenating sparse | |
890 matrices, especially larger collections, is now significantly more | |
11111 | 891 efficient. This applies to both the [] operator and the |
10536 | 892 cat/vertcat/horzcat functions. |
893 | |
11111 | 894 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
14188 | 895 for computing the singular value decomposition using svd, instead |
11111 | 896 of the default xGESVD, using the configuration pseudo-variable |
897 svd_driver. The xGESDD driver can be up to 6x times faster when | |
898 singular vectors are requested, but is reported to be somewhat less | |
10639 | 899 robust on highly ill-conditioned matrices. |
900 | |

902 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |

1147 into and over functions, and stepping one statement at a time | |
1148 (with dbstep) now works. Moving up and down the call stack with | |
1149 dbup and dbdown now works. The dbstack function is now available | |
1150 to print the current function call stack. The new dbquit function | |
1151 is available to exit the debugging mode. | |
1152 | |
1153 ** Improved traceback error messages. | |
1154 | |
1155 Traceback error messages are much more concise and easier to | |
1156 understand. They now display information about the function call | |
1157 stack instead of the stack of all statements that were active at | |
1158 the point of the error. | |

8737 | 1162 Octave now includes OOP features and the user can create their own |
1163 class objects and overloaded functions and operators. For | |
1164 example, all methods of a class called "myclass" will be found in | |
1165 a directory "@myclass" on the users path. The class specific | |
1166 versions of functions and operators take precedence over the | |
1167 generic versions of these functions. | |
1168 | |
1169 New functions related to OOP include | |
7189 | 1170 |
8737 | 1171 class inferiorto isobject loadobj methods superiorto |
1172 | |
1173 See the Octave manual for more details. | |
7038 | 1174 |
8747 | 1175 ** Parsing of Command-style Functions. |
1176 | |
1177 Octave now parses command-style functions without needing to first | |
1178 declare them with "mark_as_command". The rules for recognizing a | |
1179 command-style function calls are | |
1180 | |
1181 * A command must appear as the first word in a statement, | |
1182 followed by a space. | |
1183 | |
1184 * The first character after the space must not be '=' or '(' | |
1185 | |
1186 * The next token after the space must not look like a binary | |
1187 operator. | |
1188 | |
1189 These rules should be mostly compatible with the way Matlab parses | |
1190 command-style function calls and allow users to define commands in | |
1191 .m files without having to mark them as commands. | |
1192 | |
1193 Note that previous versions of Octave allowed expressions like | |
1194 | |
1195 x = load -text foo.dat | |
1196 | |
1197 but an expression like this will now generate a parse error. In | |
1198 order to assign the value returned by a function to a variable, | |
1199 you must use the normal function call syntax: | |
1200 | |
1201 x = load ("-text", "foo.dat"); | |
1202 | |
8737 | 1203 ** Block comments. |
1204 | |
8747 | 1205 Commented code can be between matching "#{" and "#}" or "%{" and |
1206 "%}" markers, even if the commented code spans several line. This | |
1207 allows blocks code to be commented, without needing to comment | |
1208 each line. For example, | |
5814 | 1209 |
8747 | 1210 function [s, t] = func (x, y) |
1211 s = 2 * x; | |
1212 #{ | |
1213 s *= y; | |
1214 t = y + x; | |
1215 #} | |

1271 conversions between cells, structs and cs-lists. This usually reduces |
8755 | 1272 both time and memory consumption. |
9128 | 1273 Also, Octave will now attempt to detect and optimize usage of a vector |
1274 as a stack, when elements are being repeatedly inserted at/removed from | |
1275 the end of the vector. | |
8755 | 1276 |
8738 | 1277 ** Improved performance for reduction operations. |
1278 | |
8755 | 1279 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all, |

1284 The performance of sort has been improved, especially when sorting | |
10453 | 1285 indices are requested. An efficient built-in issorted |
1286 implementation was added. The sortrows function now uses a more | |

1296 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
10453 | 1297 increment are allowed and can be constructed using the built-in |
1298 function `ones'. | |
9006 | 1299 |
1300 ** Various performance improvements. | |
1301 | |
10453 | 1302 Performance of a number of other built-in operations and functions |
1303 was improved, including: | |
9006 | 1304 |
1305 * logical operations | |
1306 * comparison operators | |
1307 * element-wise power | |
1308 * accumarray | |

1311 * isinf | |

1315 * strcmp | |
1316 | |
8737 | 1317 ** 64-bit integer arithmetic. |
1318 | |
1319 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
1320 supported, with saturation semantics like the other integer types. | |
1321 Performance of most integer arithmetic operations has been | |
1322 improved by using integer arithmetic directly. Previously, Octave | |
1323 performed integer math with saturation semantics by converting the | |
1324 operands to double precision, performing the operation, and then | |
1325 converting the result back to an integer value, truncating if | |
1326 necessary. | |
1327 | |
8885 | 1328 ** Diagonal and permutation matrices. |
1329 | |
1330 The interpreter can now treat diagonal and permutation matrices as | |
1331 special objects that store only the non-zero elements, rather than | |
1332 general full matrices. Therefore, it is now possible to construct | |
1333 and use these matrices in linear algebra without suffering a | |
1334 performance penalty due to storing large numbers of zero elements. | |
1335 | |
1336 ** Improvements to fsolve. | |
1337 | |
1338 The fsolve function now accepts an option structure argument (see | |
1339 also the optimset function). The INFO values returned from fsolve | |
1340 have changed to be compatible with Matlab's fsolve function. | |
1341 Additionally, fsolve is now able to solve overdetermined systems, | |
1342 complex-differentiable complex systems, systems with a sparse | |

8737 | 1346 ** Improvements to the norm function. |
1347 | |
1348 The norm function is now able to compute row or column norms of a | |
1349 matrix in a single call, as well as general matrix p-norms. | |
1350 | |
1351 ** New functions for computing some eigenvalues or singular values. | |
1352 | |
1353 The eigs and svds functions have been included in Octave. These | |
1354 functions require the ARPACK library (now distributed under a | |
1355 GPL-compatible license). | |

8885 | 1398 ** Changes to strcat. |
1399 | |
1400 The strcat function is now compatible with Matlab's strcat | |
1401 function, which removes trailing whitespace when concatenating | |
1402 character strings. For example | |
1403 | |
1404 strcat ('foo ', 'bar') | |
1405 ==> 'foobar' | |
1406 | |
1407 The new function cstrcat provides the previous behavior of | |
1408 Octave's strcat. | |
1409 | |

1412 The help system has been mostly re-implemented in .m files to make |
8885 | 1413 it easier to modify. Performance of the lookfor function has been |
1414 greatly improved by caching the help text from all functions that | |
1415 are distributed with Octave. The pkg function has been modified | |
1416 to generate cache files for external packages when they are | |
1417 installed. | |
