Hi all,

Is there a python module that can read (sparse) matrices in
one of the formats listed at 
http://math.nist.gov/MatrixMarket/formats.html. I am especially 
interested in Harwell-Boeing format, which is used at 
http://www.cise.ufl.edu/research/sparse/matrices/.

btw, the C (even in scipy: scipy/Lib/sparse/SuperLU/*readhb.c) or 
fortran (in UMFPACK package: UMFPACK/UMFPACK/Demo/readhb.f) functions 
are well available, just the wrappers I cannot find.

I am going to swig'em myself because I need it - I posted this question 
in order to prevent (re)inventing wheels :)
