oneapi::mkl::rng::laplace
Generates random numbers with Laplace distribution.
Description
The oneapi::mkl::rng::laplace class object is used in the oneapi::mkl::rng::generate function to provide random numbers with Laplace distribution with mean value (or average) a and scalefactor ( b, β), where . The scalefactor value determines the standard deviation as
The probability density function is given by:
The cumulative distribution function is as follows:
