Method Detail

getMaximumIterations

public int getMaximumIterations()

Access the maximum number of iterations.

Returns:

the maximum number of iterations.

getMaximumRelativeError

public double getMaximumRelativeError()

Access the maximum relative error.

Returns:

the maximum relative error.

iterate

public void iterate(IterativeMethod.IterativeState state)
             throws NumericException

Perform the iterative evaluation. state is used to manage state between iterations.

Parameters:

state - the state for this iterative method evaluation.

Throws:

NumericException - if a solution to the iterative method can not be computed.

setMaximumIterations

public void setMaximumIterations(int iterations)

Modify the maximum number of iterations.

Parameters:

iterations - the new maximum number of iterations value.

setMaximumRelativeError

public void setMaximumRelativeError(double error)

Modify the maximum relative error.

Parameters:

error - the new maximum relative error.
