Random number functions

array's random number functions allow arrays to be filled with random numbers efficiently in a single call. Most of these functions use the array_urand uniform random object (of type urand), which is accessible from TCL. The fillgrand() function makes use of the TCL accessible array_grand object, which is of type gaussrand.

• void fillrand(array x)

  Fill x with random numbers from the uniform distribution over

• void fillprand(array x)

  Fill x with random numbers from the Poisson distribution

• void fillgrand(array x)

  Fill x with random numbers from the Gaussian distribution

• void fill_unique_rand(array x, int max)

  Fill x with random integers from the range [0..max] such that no two integers are the same.
