oneapi::mkl::rng::uniform (Continuous)

Generates random numbers with uniform distribution.

Description

The class object is used in oneapi::mkl::rng::generate function to provide random numbers uniformly distributed over the interval [a, b), where a, b are the left and right bounds of the interval, respectively, and a, b∈R ; a < b.

The probability density function is given by:

F_{a, b}(x) = \begin{cases} \frac{1}{b-a}, & x \in [a, b)\\ 1, & x \notin [a, b) \end{cases}, -\infty < x < +\infty

The cumulative distribution function is as follows:

F_{a, b}(x) = \begin{cases} 0, & x < a \\ \frac{x-a}{b-a}, & a \leq x < b \\ 1, & x \geq b \end{cases}, -\infty < x < +\infty
