Detailed Description

Random number source.

Generate random values from different distributions. Currently, only Gaussian and uniform are enabled.

Parameters:

type	the random distribution to use (see gr_noise_type.h)
ampl	a scaling factor for the output
seed	seed for random generators. Note that for uniform and Gaussian distributions, this should be a negative number.
samples	number of samples to pre-generate.
