Pysparse is a fast sparse matrix library for Python. It provides several sparse matrix storage formats and conversion methods. It also implements a number of iterative solvers, preconditioners, and interfaces to efficient factorization packages. Both low-level and high-level interfaces are available, each with different strengths. The only requirement to install and use Pysparse is Numpy. Be sure to check the Documentation for examples.
The complete documentation is also available in PDF format.
Pysparse is available in source form from SourceForge directly from the Git repository using
git clone git://pysparse.git.sourceforge.net/gitroot/pysparse/pysparseor from the Python Package Index:
pip install numpy pip install pysparse
