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!
