oneapi::mkl::rng::device::uniform
(Continuous)¶
Generates random numbers with uniform distribution.
Syntax
template<typename Type, typename Method> class uniform { public: using method_type = Method; using result_type = Type; uniform(): uniform((Type)0.0, (Type)1.0){} explicit uniform(Type a, Type b); explicit uniform(const param_type& pt); Type a() const; Type b() const; param_type param() const; void param(const param_type& pt); };Include Files

Description
The
oneapi::mkl::rng::device::uniform
class object is used in theoneapi::mkl::rng::device::generate
function to provide random numbers uniformly distributed over the interval [a
,b
), wherea
,b
are the left and right bounds of the interval, respectively, anda
,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
