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 a, β∈R ; β > 0.
The probability density function is given by:
The cumulative distribution function is as follows:
Intel’s compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
