Detailed Description

Implements the solution of linear system of equation in the form $A\cdot x=b$ using solvers from MKL Pardiso.

It will not work with Pardiso 5.0. Only works with the CSC (compressed sparse column) sparse matrix implementation.

virtual

Solves the given sparse linear system of equations $A\cdot x=b$ .

Parameters

A	Coefficient matrix.
b	Right hand side.
x	Solution array.

Returns: Status of the solver.

Todo:: pardisoinit seems to write outside this array

Todo:: I might be misunderstanding something, but this iterative solver still does a full factorization. No options for incomplete factorizations.

Todo:: I have no idea if this is suitable value. Examples use 2. / Mikael

Todo:: This is not included in the table of options for some reason!
