Sparse matrix data structures?

[Joze]

Hi,

Are there any Python packages implementing some of the most usual data
structures for sparse matrices (coordinates, compressed rows,
compressed columns, etc.)? I found SparsePy on the web, but it doesn't
seem to be maintained any more, and the link to the source is broken.
How well do these integrate with numarray and/or SciPy?

Thanks for the help!
Joe.
