Description

The onemkl::rng::multinomial class object is used in the onemkl::rng::generate function to provide multinomially distributed random numbers with ntrial independent trials and k possible mutually exclusive outcomes, with corresponding probabilities pi, where pi∈R; 0 ≤pi≤ 1, m∈N, k∈N.

The probability distribution is given by:

Input Parameters

Name	Type	Description
method	onemkl::rng::method	Generation method. The specific values are as follows: onemkl::rng::poisson_inverse See brief descriptions of the methods in Distributions Template Parameter onemkl::rng::method Values.
ntrial	std::int32_t	Number of independent trials m.
p	std::vector<double>	Probability vector of possible outcomes (k length).
