ptolemy.math.SignalProcessing.GaussianSampleGenerator

All Implemented Interfaces:

DoubleUnaryOperation

Enclosing class:

SignalProcessing

public static class SignalProcessing.GaussianSampleGenerator
extends java.lang.Object
implements DoubleUnaryOperation

This class generates samples of a Gaussian function with the specified mean and standard deviation. The function computed is :

  h(t) = (1/(sqrt(2 * PI) * stdDev) *
         exp(-(t - mean)2 / (2 * stdDev2))
