Probability Density Function

$\text{[math]}$

Parameters

Parameter	Type	Description	Input/Output
len	int	Length of the input and output.	Input
lambda	double	Lambda parameter.	Input
dst	Pointer to data of the int type	Pointer to the result.	Output
Policy	Pointer to data of the VslPolicy type	Pointer to the random number generator structure.	Input
Normal_method	N01type enumeration	Algorithm for generating normal distribution.	Input

Dependency

Example

#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include "kvsl.h"
int main()
{
    VslPolicy *policy;
    kml_vsl_init(&policy, LECUYER_CMRG, time(NULL));
    int len = 10;
    int *dst = (int *)malloc(sizeof(int) * len);
    int a = kml_vsl_rpois(policy, BOX_MULLER, len, dst, 10);
    for (int i = 0; i < len; i++) {
        printf("%d ", dst[i]);
    }
