Examples

EX1

//This example is to generate pseudo-random numbers from an F-distribution
int frnd_ex1()
{
    int n = 10;
    vector v( n );
 
    int df1 = 2;
    int df2 = 3;
        
    int nRet = frnd( v, n, df1, df2);
 
    if(0 != nRet)
    	return 0;
    
    for(int i=0;i<n;i++)
        printf("v[%d]: %f\n",i, v[i]);
