Residue Method's Code in C and MatLab | Congruential Method Code

Details:

We need the generate random numbers using Residue method. How do we generate that random number?

Solution:

Random Number generation code in C using Residue Method:

/**
    Code    : Residue/Congruential Method in C
    Author  : Maniruzzaman Akash<manirujjamanakash@gmail.com>
**/

#include<stdio.h>
int main(){
    //r(i) = (ar(i-1) + b ) modulo m
    int random[1000], maxLimit, i, n;
    printf("First Random Number or seed : ");
    scanf("%d", &random[0]);

    printf("What is the maximum limit : ");
    scanf("%d", &maxLimit);

    printf("How many eandom Number you want to generate : ");
    scanf("%d", &n);

    int a = 19, b = 1;

    printf("\nRandoms are : ");
    for(i = 1; i <= n; i++){
        //
        random[i] = ( a * random[i - 1] + b ) % maxLimit;
        printf("%d ", random[i]);
    }
    printf("\n");
}

Random Number generation code in Matlab using Residue Method:

a=input('Please Enter the value of a : ');
b=input('Please Enter the value of b : ');
m=input('Please Enter the value of m : ');
r=input('Please Enter the value of seed or r : ');


totalNumber = input('Number of Random Numbers want to generate : ');
R = zeros();

for i = 1:totalNumber
    r = mod(a*r +b, m);
    R(i) = r;
    fprintf('%4.0f ', R(i));
end
fprintf('\n');

Formula/Algorithm of residue

    //r(i) = (ar(i-1) + b ) modulo m

Simple One Line Instruction, nothing to say here.
