Detailed Description

Integer uniform distribution.

Example: Generation of random uniformly distributed integers in the interval [0,10].

#include "itpp/sigproc.h"
 
int main() {
 
I_Uniform_RNG gen(0, 10);
 
cout << gen() << endl; // prints a random integer
cout << gen(10) << endl; // prints 10 random integers
}
