Changes:
- Code cleanup. Polynomial division routine is now very easy to use.
- Renamed "WINDOWS" define to "CYGWIN".
- Added "set preserve_roots" option.
- Added modulus solving.

Unfortunately, guile{,14}/buildlink3.mk directly includes it, and I don't
know which dependencies actually need libltdl, so it was a recursive bump.
Hopefully this recursive inclusion can be ripped out of
guile{,14}/buildlink3.mk at some point and bubble down to dependencies that
actually use libltdl, avoiding this headache in the future....

|
Changes:
- Added "code integer" command, which outputs working C code with integer
variables.
- Changed makefile to use libncurses instead of libcurses.
- Added more simplification rules for modulus.

as it's only used internally by bsd.prefs.mk.
* Make _PKGSRCDIR a public variable by renaming it to PKGSRCDIR.
Also, generate its value from ${_PKGSRC_TOPDIR} so it's less fragile
than the old method of stripping off the last two components of
${.CURDIR}. PKGSRCDIR may now be used after bsd.prefs.mk is defined.
* Change all references to _PKGSRCDIR to PKGSRCDIR.

Changes:
Changed sum and product commands to not create another equation if the
result is a constant. If the result is a constant, it is just displayed.
Mathomatic now approximates -1^(2^.5) and the like.
Added modulus (%) operator.
Added simplification of univariate modulus expressions.
Changed univariate modulus simplification to multivariate, integer only
simplification.

in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.

v4.1
COSMETIC/USABILITY IMPROVEMENTS
- The File->Description dialog now updates automatically if you leave it open
while loading a new pattern file. Also, any previous description dialog is
closed when you open a new one.
- GtkLife now issues a warning dialog if it appears the application was not
propery installed (i.e., "make" without "make install").
- GtkLife now issues a warning dialog if the configured pattern collection
is not found.
BUG FIXES
- Fixed a bug that prevents the start/stop button from changing color when
Gtk+ has debugging enabled (thanks to James Gregory for reporting).
- Fixed stair-stepping effect when drawing diagonal lines.
MISCELLANEOUS
- Better ChangeLog :-)
v4.0
NEW FUNCTIONALITY
- The world size has been bumped up to 1 million x 1 million.
- Added View->Find Active Cells, to locate a live (and preferably active)
region and center on it.
- gtklife has a new default file format, GLF, which is similar to RLE.
- gtklife can now handle multiple file formats: Life 1.05 (the original
format), Life 1.06, RLE, XLife, and GLF. File type is auto-detected when
loading. Information on file formats was added to the "File Handling"
section of the documentation, and a page was added giving detailed
information on the GLF format.
- You can now set a per-session pattern directory
(File->Change Pattern Collection) as well as a default pattern directory
(Preferences/File/Default Pattern Collection).
- Sidebar patterns can now be bundled into sub-directories. Directories will
be displayed with trailing slashes. Click on a directory name to display
its contents in a clickable list beneath the sidebar.
- You can now specify a pattern collection directory on the command line
(previously only individual patterns could be loaded via command line).
- The pattern description has been made unbounded in length and width. An
error will occur if you attempt to save a pattern with a too-large
description to a LIF or RLE pattern file.
COSMETIC/USABILITY IMPROVEMENTS
- Mouse wheel over the description text box now scrolls the description
(previously you had to hover the mouse over the scrollbar).
- The color picker in Preferences now uses the contents (if any) of the
corresponding text entry as its starting color.
- Recent files in the File menu now display full path as a tooltip.
- Sidebar scrollbar is now only displayed when needed.
PATTERN COLLECTION CHANGES
- A new pattern collection, JSLife by Jason Summers, is now available as an
option. The sidebar can be set to display the original LifeP, JSLife, or
a custom collection of your own.
- Patterns were reorganized into a hierarchical format.
- Patterns were renamed to be more human-readable.
- Patterns were converted to GLF for speed of loading.
- Pattern descriptions were reformatted.
- Paul Rendell's Turing Machine pattern was added to the LifeP collection.
- Added a longer description to the Unit Cell pattern.
- Now that we have a command to locate active cells, re-centered the Jaws
pattern.
- Note: Due to a minor change in the config file, any custom pattern
directory that you have chosen previously will be reset.
DOCUMENTATION IMPROVEMENTS
- Fixed broken link to the Scientific American article in help.
MISCELLANEOUS
- The install process now deletes any existing patterns bundle before copying
over the new patterns.
- Added new nifty program icons based on the "pulsar".

Changes since 11.3c:
Improved eliminate command error handling.
Added "eliminate all" command.
Code cleanup.
Man pages for the prime number tools were contributed
by David Moreno Garza. Many thanks.
Renamed the Mathomatic directory in the source tarball to
"mathomatic-`cat VERSION`".
Added several comments to the source code.
Renamed prime number tools to "matho-*".
Improvement to full simplification.
Tried something new with uf_simp() that fixed a problem with Mathomatic
solve complicating expressions.
Minor bugfix to eliminate command.

All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".

* Generated tarball distribution for GNOME 2.8 (Final).

This release adds changes to better support compiling under cygwin,
improved custom function support, including the addition of the
pmodm127 example and config("compile_custom") and config("allow_custom")
calls, and a missing display help file. It fixes configuration
state hashing, document typos, calc -d (to disable printing of the
leading ~), and some compilation warnings reported under OS X.

installed files.
- libtoolize a few more lines which seem to have been missed in the original
libtoolization.
- enable loading of shared objects which lets the various .oct files installed
by octave-forge actually work instead of just the .m files.

in NetBSD-current. It may not be too hard for a c++ programmer to fix.
Should address recently noted bulk build failures.

which are the full option names used to set rpath directives for the
linker and the compiler, respectively. In places were we are invoking
the linker, use "${LINKER_RPATH_FLAG} <path>", where the space is
inserted in case the flag is a word, e.g. -rpath. The default values
of *_RPATH_FLAG are set by the compiler/*.mk files, depending on the
compiler that you use. They may be overridden on a ${OPSYS}-specific
basis by setting _OPSYS_LINKER_RPATH_FLAG and _OPSYS_COMPILER_RPATH_FLAG,
respectively. Garbage-collect _OPSYS_RPATH_NAME and _COMPILER_LD_FLAG.

changes:
Bug fixes and addition of weakreferences (weakref module)

The octave-forge project contains functions for Octave which are not in
the main distribution. While the main Octave distribution is
conservative about accepting new functions and changes, octave-forge is
very open. As a result, be prepared for some lower quality code and
more rapidly changing interfaces to the functions in octave-forge.

and also add GCC_REQ=3.0 as this doesn't build correctly with my 2.95.3
on NetBSD/alpha.
|
|
|
|
notable changes besides bugfixes are:
** Multifit routines now handle iterations where |f| is already
minimised to zero, without division by zero.
** Numerical derivatives should now be calculated using the
gsl_deriv_forward, gsl_deriv_central and gsl_deriv_backward functions,
which accept a step-size argument in addition to the position x. The
original gsl_diff functions (without the step-size) are deprecated.
** The tridiagonal matrix solvers gsl_linalg_solve_symm_tridiag,
gsl_linalg_solve_tridiag, gsl_linalg_solve_symm_cyc_tridiag,
gsl_linalg_solve_cyc_tridiag now use the GSL_ERROR macro to report
errors, instead of simply returning an error code. The arguments to
these functions must now use exact lengths with no additional
elements. For cyclic systems all vectors must be of length N, for
tridiagonal systems the offdiagonal elements must be of length N-1.
** The singular value decomposition routines gsl_linalg_SV_decomp and
gsl_linalg_SV_decomp_mod now handle the SVD of a column vector (N=1,
arbitrary M), which can occur in linear fitting.
** Added Stefan-Boltzmann constant and Thomson cross section to
physical constants

Changes:
"factor number" command now accepts more than one integer.
Added file "mathomatic.ico".
Added temporary fix for 64 bit longs.
Added file "VERSION" which contains the version number of Mathomatic.
"makefile" modified.
Renamed "lgpl.txt" to "LICENSE.txt".
"make install" now installs all HTML files in "/usr/local/doc/mathomatic".
Added compile-time define "TIMEOUT_SECONDS".
Useful for limiting the amount of time Mathomatic can run as a CGI.

LibTomMath provides highly optimized and portable routines for a
vast majority of integer based number theoretic applications
(including public key cryptography). LibTomMath is not a cryptographic
toolkit itself but it can be used to write one [Used in LibTomCrypt
for RSA, DH and ECC public key routines].
|
|
Changes:
Proper exit after error reading files on the command line.
Added code to preserve roots of integers, if the result is irrational.
Fixed "calculate >filename".
Made "+/-2^.5" work as expected.
Code cleanup.
Full simplify added for every loop of taylor command.
Removed "replace temp" option, so that the "temp" variable can be renamed.

important changes:
- Ports of Numeric functions
A bunch of Numeric functions were ported to numarray in the new
libnumeric module. To get these import from numarray.numeric. Most
notable among these are put, putmask, take, argmin, and argmax. Also
added were sort, argsort, concatenate, repeat and resize. These are
independent ports/implementations in C done for the purpose of best
Numeric compatibility and small array performance. The numarray
versions, which handle additional cases, still exist and are the
default in numarray proper.
- Faster matrix multiply
The setup for numarray's matrix multiply was moved into C-code. This
makes it faster for small matrices.
- bug fixes

# XXX: following comment still true for buildlink3?
# R does ugly things in the configure to get the default list of arguments
# for linking Fortran, which exposes the buildlink2 tricks so clean up
# afterwards
