Description

Generates an array of random numbers from a Cauchy distribution, seeds and generator number passed explicitly

Syntax

int caurnd( double * v, uint n, double xmed, double semiqr )

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
xmed: [input] The median, a, of the distribution
semiqr: [input] The semi-interquartile range, b, 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 caurnd_ex1()
{
    int n = 10;
    vector v( n );

    double xmed = 1.0;
    double semiqr = 2.0;
					
    int nRet = caurnd( v, n, xmed, semiqr);
 
    if(0 != nRet)
		return 0;
    
    for(int i=0;i<n;i++)
        printf("v[%d]: %f\n",i, v[i]);
    
    return 1;
}
