Class prob_dens_uniform (o2scl)

O2scl : Class List

class o2scl::prob_dens_uniform : public o2scl::prob_dens_frange

A uniform one-dimensional probability density over a finite range.

A flat distribution given by \( P(x)=1/(b-a) \) for \( a<x<b \), where \( a \) is the lower limit and \( b \) is the upper limit.

This class is experimental.
