Method Detail

getErrAmplitude

public double getErrAmplitude()

Returns the magnitude of the error sinusoid.

Returns:

the magnitude of the error sinusoid.

quickCompute

public double quickCompute(double[] x)

Description copied from class: BasicScalarFunction

Compute method without dimension checking. All subclasses must implement this method: it is the core method that defines the function.

Specified by:

quickCompute in interface ScalarFunction

Overrides:

quickCompute in class Hartman6

Parameters:

x - the given input.

Returns:

the output corresponding to the given input.

setErrAmplitude

public void setErrAmplitude(double amp)

Sets the magnitude of the error sinusoid.

Parameters:

amp - the magnitude of the error sinusoid.

computeError

protected double computeError(double[] x)

Parameters:

x -

Returns:
