oneapi::mkl::rng::poisson_v

Generates Poisson distributed random values with varying mean.

Description

The
oneapi::mkl::rng::poisson_v
class object is used in the
oneapi::mkl::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:
LaTex Math image.
The cumulative distribution function is as follows:
