Method Detail

setPreconditioner

public void setPreconditioner(Preconditioner M)

Description copied from interface: IterativeSolver

Sets preconditioner

Specified by:

setPreconditioner in interface IterativeSolver

Parameters:

M - Preconditioner to use

getPreconditioner

public Preconditioner getPreconditioner()

Description copied from interface: IterativeSolver

Gets preconditioner

Specified by:

getPreconditioner in interface IterativeSolver

Returns:

Current preconditioner

getIterationMonitor

public IterationMonitor getIterationMonitor()

Description copied from interface: IterativeSolver

Gets the iteration monitor

Specified by:

getIterationMonitor in interface IterativeSolver

Returns:

Current iteration monitor

setIterationMonitor

public void setIterationMonitor(IterationMonitor iter)

Description copied from interface: IterativeSolver

checkSizes

protected void checkSizes(Matrix A,
                          Vector b,
                          Vector x)

Checks sizes of input data for IterativeSolver.solve(Matrix, Vector, Vector). Throws an exception if the sizes does not match.
