373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	15
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	16 ** Octave 3.4.1 is primarily a bug fixing release.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	17
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	18 ** IMPORTANT note about binary incompatibility in this release:
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	19
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	20 Binary compatibility for all 3.4.x releases was originally planned,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	21 but this is impossible for the 3.4.1 release due to a bug in the way
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	22 shared libraries were built in Octave 3.4.0. Because of this bug,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	23 .oct files built for Octave 3.4.0 must be recompiled before they
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	24 will work with Octave 3.4.1.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	25
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	26 Given that there would be binary incompatibilities with shared
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	27 libraries going from Octave 3.4.0 to 3.4.1, the following
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	28 incompatible changes were also made in this release:
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	29
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	30 * The Perl Compatible Regular Expression (PCRE) library is now
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	31 required to build Octave.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	32
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	33 * Octave's libraries and .oct files are now installed in
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	34 subdirectories of $libdir instead of $libexecdir.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	35
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	36 Any future Octave 3.4.x release versions should remain binary
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	37 compatible with Octave 3.4.1 as proper library versioning is now
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	38 being used as recommended by the libtool manual.

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	40 ** The following functions have been deprecated in Octave 3.4.1 and will
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	41 be removed from Octave 3.8 (or whatever version is the second major

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	64 Summary of important user-visible changes for version 3.4:
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	65 ---------------------------------------------------------
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	66
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	67 ** BLAS and LAPACK libraries are now required to build Octave. The
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	68 subset of the reference BLAS and LAPACK libraries has been removed
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	69 from the Octave sources.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	70
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	71 ** The `lookup' function was extended to be more useful for
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	72 general-purpose binary searching. Using this improvement, the
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	73 ismember function was rewritten for significantly better
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	74 performance.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	75
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	76 ** Real, integer and logical matrices, when used in indexing, will now
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	77 cache the internal index_vector value (zero-based indices) when
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	78 successfully used as indices, eliminating the conversion penalty for
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	79 subsequent indexing by the same matrix. In particular, this means it
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	80 is no longer needed to avoid repeated indexing by logical arrays
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	81 using find for performance reasons.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	82
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	83 ** Logical matrices are now treated more efficiently when used as
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	84 indices. Octave will keep the index as a logical mask unless the
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	85 ratio of true elements is small enough, using a specialized
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	86 code. Previously, all logical matrices were always first converted
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	87 to index vectors. This results in savings in both memory and
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	88 computing time.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	89
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	90 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	91 functions for better performance. These functions are now faster,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	92 can deliver more economized results for ranges, and can reuse the
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	93 index cache mechanism described in previous paragraph.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	94
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	95 ** The built-in function equivalents to associative operators (`plus',
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	96 `times', `mtimes', `and', and `or') have been extended to accept
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	97 multiple arguments. This is especially useful for summing
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	98 (multiplying, etc.) lists of objects (of possibly distinct types):
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	99
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	100 matrix_sum = plus (matrix_list{:});
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	101
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	102 ** An FTP object type based on libcurl has been implemented. These
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	103 objects allow ftp connections, downloads and uploads to be
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	104 managed. For example,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	105
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	106 fp = ftp ("ftp.octave.org);
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	107 cd (fp, "gnu/octave");
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	108 mget (fp, "octave-3.2.3.tar.bz2");
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	109 close (fp);
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	110
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	111 ** The default behavior of `assert (observed, expected)' has been
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	112 relaxed to employ less strict checking that does not require the
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	113 internals of the values to match. This avoids previously valid
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	114 tests from breaking due to new internal classes introduced in future
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	115 Octave versions.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	116
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	117 For instance, all of these assertions were true in Octave 3.0.x
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	118 but false in 3.2.x due to new optimizations and improvements:
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	119
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	120 assert (2linspace (1, 5, 5), 2(1:5))
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	121 assert (zeros (0, 0), [])
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	122 assert (2*ones (1, 5), (2) (ones (1,5)))
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	123
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	124 ** The behavior of library functions `ismatrix', `issquare', and
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	125 `issymmetric' has been changed for better consistency.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	126
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	127 * The `ismatrix' function now returns true for all numeric,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	128 logical and character 2-D or N-D matrices. Previously, `ismatrix'
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	129 returned false if the first or second dimension was zero.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	130 Hence, `ismatrix ([])' was false,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	131 while `ismatrix (zeros (1,2,0))' was true.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	132
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	133 * The `issquare' function now returns a logical scalar, and is
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	134 equivalent to the expression
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	135
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	136 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x)
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	137
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	138 The dimension is no longer returned. As a result, `issquare ([])'
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	139 now yields true.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	140
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	141 * The `issymmetric' function now checks for symmetry instead of

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	302 Since Octave uses compressed column storage for sparse matrices,

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	307 Further, it is now possible to pre-allocate a sparse matrix and
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	308 subsequently fill it by assignments, provided they meet certain
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	309 conditions. For more information, consult the `spalloc' function,
