* What is new in gsl-0.7:
** Linux/PowerPC should now be well supported.
** Header files for common physical constants have been added.
** Functions linear and nonlinear regression in one or more dimensions
are now available.
** Vector and matrix views now have access to the address of the
underlying block for compatibility with VSIPL (www.vsipl.org).
** There is a new library for generating low-discrepancy quasi-random
sequences.
** The seeding procedure of the default random number generator
MT19937 has been updated to match the 10/99 release of the original
code. This fixes a weakness which occurred for seeds which were
powers of 2.
** The blas library libgslblasnative has been renamed libgslblas to avoid
confusion with system blas library
o add @exec/@unexecinstall-info directives to PLIST
o slightly change the path's for the documentation
(share/doc/octave instead of share/octave/doc etc.)
o install html docs into share/doc/html/octave
first component is now a package name+version/pattern, no more
executable/patchname/whatnot.
While there, introduce BUILD_USES_MSGFMT as shorthand to pull in
devel/gettext unless /usr/bin/msgfmt exists (i.e. on post-1.5 -current).
Patch by Alistair Crooks <agc@netbsd.org>
to be bug fixes mostly, plus a couple of new features:
* Release 'Mini-Morten' -- a cute little thing of
about 3k She leaks, though. (Congratulations !)
* Reworking plugin architecture to support JIT loading
* Improve scrollbar and enable optional live scrolling
* Add a sample implementation of python based scripting
The API is written in sand so don't get comfortable
* Enable indent from left and right
* Persist sheet prefs
Version 1.31 (Released 8 Mar 2001)
----------------------------------
USER-VISIBLE CHANGES
- copying an object array (see help voids) is now "deep" copy rather than "shallow" copy.
This means that when an object array is assigned to another variable, a completely new
copy is made (before, only the first array level was copied). Mostly this won't affect
you at all because (1) you are using object arrays only if you are using voids() in some
phase in your program, (2) if you are, then you are probably using only single-level
object array. The old behaviour was simply stupid. Object arrays are a crude but working
mechanism for using heterogeneous combined types in Tela; the only relevant function
(in the present Tela version) is voids(), which acts as a constructor for such things.
Thanks to Ch. Spiel for suggesting this change (object.C).
- quit() and exit() now accept input argument (the exit value) (std.ct)
- sort() function now accepts second input argument (user-defined comparison function) (std.ct)
(old function still available as sort_old in case of problems).
- slight change in semantics of --shared option for telakka (telakka.in)
The above were contributed by Christoph Spiel <cspiel@hammersmith-consulting.com>
- added incomplete gamma and beta functions (specfun.t)
(specfun.t not autoloaded, but after source("specfun.t") functions are available).
- added function polymul and added polyadd,polymul to autoload (poly.t,telainit.t)
- added function applyfilter (numerics.ct)
- added functionwise profiling option (tela -p) (tela.C,prg.C)
BUG FIXES
- doing dot product (**) of two zero-length integer vectors produced a LAPACK error message
and Tela quit (la.ct)
- tree.C:DeleteObjects() accessed memory after it being freed, which however did not cause
any problems in practice (unless using malloc debug libraries), but is anyway now fixed
INTERNAL CHANGES
- Some modernizations in configure script (e.g., now tries to link with
libatlas by default instead of libblas if available) (configure.in)
PARI-GP is a package which is aimed at efficient computations in
number theory, but also contains a large number of other useful
functions. It is somewhat related to a Computer Algebra System, but
is not really one since it treats symbolic expressions as mathematical
entities such as matrices, polynomials, series, etc..., and not as
expressions per se. However it is often much faster than other CAS,
and contains a large number of specific functions not found elsewhere,
essentially for use in number theory.
This package can be used in an interactive shell (GP) or as a C/C++
library (PARI). It is free software, in the sense of freedom AND 'free
of charge'.
For a changelog, I didn't find more than:
Numeric 17.3.0 is intended to be the last release before adding
capabilities supported by Python 2.1. This is a routine catch-up to CVS
release.
using the newest PNG library won't work on system with an older one. To
prevent such problems with precompiled binary packages require at least
"png-1.0.9nb1" in all dependences.
Tela (TEnsor LAnguage) is a scientific computing language and
environment. It is mainly targeted for prototyping large-scale
numerical simulations and doing pre- and postprocessing for them, and
it replaces a compiled language like C++ or Fortran in this
respect. The feature set is therefore biased to operations needed in
partial differential equation solvers. A relatively complete graphics
is included via a separate program (PlotMTV). Tela uses HDF format as
native save/load format. It can also read/write Matlab binary files
and some ASCII files.
Tela is generally 2-4 times faster than Matlab, the extremeties
encountered so far are 0.9-11. Even though Tela is mainly a
prototyping and development environment, modest-size 2D simulations
can be run in modern (1994) desktop workstations while preserving
"interactive" response times. Only large 2D or 3D simulations must
usually be coded in C or Fortran and run on supercomputers.
