Random number source.
Generate random values from different distributions. Currently, only Gaussian and uniform are enabled.
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. |
