Matrix package for Python / News: Recent posts

This is a long overdued release of tar.gz files for what has been in CVS for months.

Version 0.4.0 is mainly a clean up release.

Enhancements at gplot, ~op operators, kalman filter, interact, etc.

A new subpackage DynSys is added, currently consisting of a single module kalman.py which implements a stochastic linear system with kalman filtering. See its self test and tests/test_kalman.py for usage and demo.

Currently these are available in CVS only.

Many changes are made in this release. Please read the Release Notes. Some main points:
The methods .T .H .I .C etc no longer not need ()
Major bug fix for mfunc
Finding functions by lookfor(keyword).
histogram plotting.
elementwise comparisons.
docstrings for all functions.
...

We now have a patch to add new operators so that both matrix and elementwise operations are denoted concisely, but we need to decide on the exact usage. I've initiated a discussion in the comp.lang.python news group. Please voice your opinions there. Thanks.

This now definitely works in Windows NT, as I have tested. Just 'make installmod' is sufficient for use in Python.

Under CygWin, simply typing 'make install' get me as far as generating the postscript docs. Had I installed ps2pdf and latex2html it would go all the way through.

Renamed gnuplot.py to gplot.py to avoid name clash with Gnuplot.py on Windows. I've taken the plunge and installed Python on wNT in order to test it myself. It's taken more time to fix Windows than to develop the package itself on Linux. Windows users please be patient and do some DIY debugging as much as you can.

Added statistical distributions.
Added demo mode.
Now should work with Windows (which is case insensitive in filenames).
And many bug fixes.

Next release will be 0.3.0

This release has many additions and improvements.
Added a console by Henning Schroeder to have a matlab-like startup
