Since the source code is available, it is (fairly) trivial to
wrap the
f77 code using f2py and g77. This will allow you to call said
functions
from within python (+scipy).
May I recommend you read the f2py tutorial? It is to be found
on
<http://www.ifi.uio.no/in228/scripting/doc/python/fc/f2py-tutorial/

Best luck

Hi Jose,
A google search on Python MatrixMarket yields
http://people.web.psi.ch/geus/pyfemax/pysparse.html
It should not be stand-alone solution for myself.
I guess, many users will benefit from the feature
(I/O of matrices in MatrixMarket or Harwell-Boeing format), if
it becomes a part of scipy.
Any suggestion ?
BTW, the Harwell-Boeing seems to be supported by scipy
http://scipy.net/cgi-bin/viewcvsx.cgi/scipy1/sparse/SuperLU/SRC/
zreadhb.c?rev=1.2
How can I invoke this function in scipy ?
A small example is appreciated.
Nils
