Detailed Description

template<typename _RealType = double>
class std::piecewise_constant_distribution< _RealType >

A piecewise_constant_distribution random number distribution.

This distribution produces random numbers $x, b_0 \leq x < b_n$ , uniformly distributed over each subinterval $[b_i, b_{i+1})$ according to the probability mass function

$\‍[ p(x | b_0, ..., b_n, \rho_0, ..., \rho_{n-1}) = \rho_i \cdot \frac{b_{i+1} - x}{b_{i+1} - b_i} + \rho_{i+1} \cdot \frac{ x - b_i}{b_{i+1} - b_i} \‍]$

for $b_i \leq x < b_{i+1}$ .

Since: C++11
