GEN21

     

    f  #     time   size    21      type     level     [arg1  [arg2]]


Description

This generates tables of different random distributions. (See also x-class noise generators.)

time and size are the usual GEN function arguments. level defines the amplitude. Note that GEN21 is not self-normalizing as are most other GEN functions. type defines the distribution to be used as follow:

Of all these cases only 9 (Beta) and 10 (Weibull) need extra arguments. Beta needs two arguments and Weibull one.

Examples


  f1 0 1024 21 1          ; Uniform (white noise)

  f1 0 1024 21 6          ; Gaussian

  f1 0 1024 21 9 1 1 2    ; Beta (note that level precedes arguments)

  f1 0 1024 21 10 1 2     ; Weibull

All of the above additions were designed by the author between May and December 1994, under the supervision of Dr. Richard Boulanger.
