oneapi::mkl::rng::exponential¶
Generates exponentially distributed random numbers.
Description¶
The oneapi::mkl::rng::exponential class object is used in oneapi::mkl::rng::generate function to provide random numbers with exponential distribution that has displacement a and scalefactor β, where 
.
The probability density function is given by:
The cumulative distribution function is as follows:
