Detailed Description

Class for generating random numbers with uniform probability density.

The algorithms and notations used are described in [14].

The following example shows how to use this class to generate 10 numbers between 0 and 5.

#include <iostream>
#include <visp3/core/vpUniRand.h>
int main()
{
for(unsigned int i=0;i<10;++i)
std::cout << 5*r() << std::endl;
}
