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 d over each subinterval $ [b_i, b_{i+1}) $ according to the probability mass function
p(x | b_0, ..., b_n, ho_0, ..., ho_{n-1})
= ho_i dot ac{b_{i+1} - x}{b_{i+1} - b_i}
+ ho_{i+1} dot ac{ x - b_i}{b_{i+1} - b_i} ] for $ b_i
