Method Detail

fun

public double fun(int n)

Description copied from interface: SignalGenerator

Return generated value for a specific sample number.

fun

public double[] fun(int n1,
                    int n2)

Description copied from interface: SignalGenerator

Return an array of samples (indexed from zero) for the sample numbers in the closed interval [n1, n2].

Parameters:
