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))
