oneapi::mkl::rng::uniform (Discrete)
Generates random numbers uniformly distributed over the interval [a, b).
Description
The oneapi::mkl::rng::uniform class object is used in oneapi::mkl::rng::generate functions to provide random numbers uniformly distributed over the interval [a, b), where a, b are the left and right bounds of the interval respectively, and a, b∈Z; a < b.
The probability distribution is given by:
The cumulative distribution function is as follows:
