Detailed Description

Implements the solution of linear system of equation in the form \( A\cdot x=b \) using solvers from Pardiso-project.org. Adapted from mklpardisosolver implementation by M. Ohman Only works with the CSC (compressed sparse column) sparse matrix implementation.

solve()

ConvergedReason oofem::PardisoProjectOrgSolver::solve ( SparseMtrx & A, FloatArray & b, FloatArray & x )

overridevirtual

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!
