trnd

Description

Generates an array of random numbers from a Student's t-distribution, seeds and generator number passed explicitly

Syntax

int trnd( double * v, uint n, int df )

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

df

[input] The number of degrees of freedom of the distribution

Return

Return NE_NOERROR(0) on success, otherwise error.

Examples

EX1

//This example is to generate pseudo-random numbers from Cauchy distribution
int trnd_ex1()
{
    int n = 10;
    vector v(n);
        double df = 5;
                                        
    int nRet = trnd( v, n, df);
    
    if(0 != nRet)
        return 0;
    
    for(int i=0;i<n;i++)
        printf("v[%d]: %f\n",i, v[i]);

    return 1;
}
