Class CountMonitor

java.lang.Object
  com.numericalmethod.suanshu.matrix.doubles.matrixtype.sparse.solver.iterative.CountMonitor

All Implemented Interfaces:

IterationMonitor

public class CountMonitor
extends java.lang.Object
implements IterationMonitor

This simple IterationMonitor monitors the number of iterates generated, hence iterations. Note that the initial guess of solution is added as the first iterate. Therefore, the count() should normally return an integer greater than or equal to 1 if the iterative method is performed without error (or breakdown).

Constructor Summary

CountMonitor()

Method Summary

void	addIterate(Vector x) Add a newly computed iterate to this monitor.
int	count() Get the number of iterates generated by the iterative algorithm.

Method Detail

addIterate

public void addIterate(Vector x)

Description copied from interface: IterationMonitor

Add a newly computed iterate to this monitor. This should also be called with the initial guess of solution.

Specified by:

addIterate in interface IterationMonitor

Parameters:

x - the new iterate

count

public int count()

Get the number of iterates generated by the iterative algorithm.

Returns:

the number of iterates
