Description

The function imsls_random_option_get retrieves the uniform (0, 1) multiplicative congruential pseudorandom number generator or the GRSR method. The uniform pseudorandom number generators use a multiplicative congruential method, with or without shuffling. The value of the multiplier and whether or not to use shuffling are determined by imsls_random_option.
