Detailed Description

Solves Ax = b using the SPARSPAK routines.

This class is derived from the MatrixSolver class and provides an interface to the SPARSPAK routines, originally developed by George and Liu, for re-ordering, factorizing, and solving via Cholesky decomposition a sparse, symmetric, positive definite set of linear equations Ax = b.
