FFTW 3.2.2
* Improve performance of some copy operations of complex arrays on
x86 machines.
* Add configure flag to disable alloca(), which is broken in mingw64.
* Planning in FFTW_ESTIMATE mode for r2r transforms became slower
between fftw-3.1.3 and 3.2. This regression has now been fixed.

SciPy 0.7.0 is the culmination of 16 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and
better documentation. There have been a number of deprecations and
API changes in this release, which are documented below. All users
are encouraged to upgrade to this release, as there are a large number
of bug-fixes and optimizations.
|
|
This minor includes numerous bug fixes, official python 2.6 support, and
several new features such as generalized ufuncs.
|

Changes since previous (3.2.0) are minor bug fixes.

Shared directories can now be created independently by the pacakges
needing them and will be removed automatically by pkg_delete when empty.
Packages needing empty directories can use the @pkgdir command in PLIST.

Changes:
- Comparisons between elements of the Expression domain are undefined.
Earlier versions gave confusing results for expressions like '\%e < \%pi',
now FriCAS will complain about '<' being undefined.
- A domain for general quaternions was added.
- Equality in Any is now more reasonable -- it uses equality from
underlying domain if available.
- Messages about loading of components are switched off by default.
- Release build benefits from parallel make.
- In Spad code a single quote now means that the following token
is a symbol.
- Reorganization of algebra sources, in particular several types
have changed (this may affect users Spad code).
Bug fixes, in particular:
- Categories with default package can be used just after definition
(fixes 1.0.6 regression).
- Plots involving 0 or 1 work now.
- Numbers in radix bigger than 10 appear correctly in TeX output.
- Fixed browser crashes when displaying some domains.
- Fix horizontal display of fractions.
- Allow local domains in conditionals (in Spad code).
- Fixed a problem with splitting polynomials and nested extensions.

o Ensure that the include/ directory exists before installing into it
(uncovered during bulk build, causing include to be a file, and
causing cascading build problems for all subsequent packages
wanting to install include files...)
o Do some other minor adjustments to placate pkglint.

Changes since 14.3.6:
- Perfected the user interface for the sum, product, and integrate
commands.
- Restored initial full simplify in the limit command for better
results, that was unintentionally removed in version 14.1.0.
- Fixed an endless loop in simplification; results look better, too.
- Added "set save" command, which makes all current session options
permanent, by saving them in "~/.mathomaticrc". "set no save"
removes this file.
- Added "mathomatic -s" option, which stands for secure mode. This is
a run-time option that disallows shelling out and writing files, and
was created for use on public servers that can't use the SECURE
compile-time define.
- Doubled the default maximum mathematical expression size to allow
larger expressions.
- A fatal compilation error when compiling with defines other than
UNIX was fixed.
- Slight improvement made to simplification; results are more simple
and stable.
- The maximum integer that can be factored has been raised from 14 to
15 decimal digits.
- Small fix made to fraction command and "simplify fraction" for
better looking fractions.
- Added a "simplify quickest" command option, which does no
unfactoring nor factoring.
- Made full simplification more efficient and simpler by cutting out
unnecessary loops.
- Improved the divide command and enabled its use in the symbolic math
library. Enabled code and variables commands in library, too.
Currently, library output of these 3 commands can only be gathered
by redirecting to a file.
- Added "set autoselect" and "set auto" options. Use "set no auto" to
always store entered expressions into equation spaces, unless it is
a command.

Non-interactive stdin is always available for reading.
Failing to set the 'stdinOwned' flag meant that you could never read from
stdin which wasn't a terminal. Oops.
commit d0604e797cf194eb025a1784766ebea8cf38ec87
Author: Keith Packard <keithp@keithp.com>
Date: Wed Mar 26 23:21:41 2008 -0700
Allow background nickle to not poll on tty ownership
When stdin is connected to a terminal but nickle is not the foreground
process on that terminal, the io code would poll to wait for ownership to
flip back to nickle so that reads could be performed without generating a
signal. Now, nickle waits until someone actually tries to read from the
terminal before starting to poll. This means that simple background
processing nickle programs will not poll every 100ms.

Remove support for non-SIGIO pipes
Older version of the kernel (before 2001) failed to generate SIGIO on pipes,
so nickle had code to poll instead. I think we can safely remove that code
now.

Avoid having the 'pretty_print' builtin show two error messages.
NamespaceLocate takes a 'complain' boolean that will print out an error
message, but the pretty_print command also raises an exception when it fails
to find the name. Two errors is at least one too many here.

The fix is suboptimal because the y2037 problem remains. It would be
better to either
-extend the "cln" lib for 64-bit integers (but the code is a mess
already) or
-split the time_t into a lower/higher part and convert them seperately,
which is less than elegant.
-add a MESSAGE telling that gnome-vfs or wget are needed to fetch
currency exchange rates automatically, so the (wrong) wget dependency
can be removed from child pkgs

#576973)
* Keep settings (show zeroes, thousands separator etc) when

Notable changes (compared to 1.0.5 version) include:
- the axiom script is no longer installed (use fricas script instead)
- some undesirable simplification are no longer done by default,
for example now asin(sin(3)) is left unevaluated
- support lambda expressions using '+->' syntax and nested functions
in Spad
- better configure, support for Dragonfly BSD
- faster bootstrap, also parallel (this does not affect speed
of release build)
Several bug fixes, in particular:
- fixed a regression introduced in 1.0.4 which caused equality
for nested products to sometimes give wrong result
- corrected fixed output of floating point numbers,
- operations on differential operators like symmetric power work now
- fixed crashes related to coercing power series
- functions returning Void can be traced

Some basic statistics on vectors (min,max,average,....).

Math::Round is a Perl module. It supplies functions to round numbers,
both positive and negative, in various ways. This may seem like an
odd thing to write a whole module for, but rounding can sometimes be
a little tricky, so I thought some people might find this useful.

CLISP and SBCL are build dependencies.
