Description

The onemkl::rng::poisson_v class object is used in the onemkl::rng::generate function to provide n Poisson distributed random numbers x_i(i = 1, …, n) with distribution parameter λi, where λi∈R; λi > 0.

The probability distribution is given by:

The cumulative distribution function is as follows:
