Description

Generates pseudo-random real numbers from the beta distribution

Syntax

int betarnd( double * v, uint n, double a, double b )

Parameters

v
[output] Pointer to a double array, which contain the results
n
[input] The number of pseudo-random numbers to be generated. n>=1
a
[input] The parameter, a, of the beta distribution
b
[input] The parameter, b, of the beta distribution

Return

Return NE_NOERROR(0) on success, otherwise error.

Examples

EX1

//This example is to generate pseudo-random numbers from beta distribution
int betarnd_ex1()
{
    int n = 10;
    vector v( n );

    double a=0.2,b=0.2;
    int nRet = betarnd( v, n, a, b);

    if(0 != nRet)
        return 0;
    
    for(int i=0;i<n;i++)
        printf("v[%d]: %f\n",i, v[i]);
   
    return 1;
}
