Examples

EX1

#include <origin.h>
#include <profiler.h>
void Profiler_ex1()
{
    Profiler tempObj; // just need to place this as 1st line in function
    
    vector vSrc;
    matrix mat;
    vSrc.SetSize(500000);
    mat.SetSize(500,1000);
    for(int n=0; n<500000; n++)//Generate 500000 random numbers
    {
    	vSrc[n] = (int)(rnd()*1000000);
    }
    mat.SetByVector(vSrc);
    vSrc.Sort();
    mat.Sort();
   
}
