Method Detail

preconditioner

void preconditioner(double[] r,
                    double[] z)
Used to compute z = M^{-1}r where M is the preconditioning matrix and r and z are arrays of length n, the order of matrix M.

Parameters:
r - an input double array of length n generated during the implementation of the solve method.
z - an output double array of length n.
