+ This provides a set of sparse matrix types for Python, with modules
+ which implement:
+ - Iterative methods for solving linear systems of equations
+ - A set of standard preconditioners
+ - An interface to a direct solver for sparse linear systems of equations
+ - The JDSYM eigensolver.
+ All of these modules are implemented as C extension modules based on
+ standard sparse and dense matrix libraries (UMFPACK/AMD, SuperLU,
+ BLAS/LAPACK) for maximum performance and robustness.
