# Multiply two matrices in node js Js program for Two Matrix Multiplication. Here mentioned other language solution.

``````/*
Node JS program for
Two matrix multiplication

// Display the element of given 2d matrix
function printRecord(matrix)
{
console.log(" ",matrix);
}

function multiplication(a, b)
{
// Get the size
var row = a.length;
var col = a.length;
// This matrix are store the result of multiplication
var result = Array(row).fill(0).map(() => new Array(col).fill(0));
for (var i = 0; i < row; ++i)
{
for (var j = 0; j < col; ++j)
{
// Set the initial value of new matrix element
result[i][j] = 0;
for (var k = 0; k < row; ++k)
{
// Multiply matrix A [i] row and [k] columns to
// the Matrix B [k] columns and [j] rows.

console.log("  Matrix A");
// Print element of matrix x
printRecord(a);

// Display resultant matrix
printRecord(result);
}

function main()
{
// Define matrix A
var a = [
[1, 2, 3],
[6, 1, 2],
[5, 4, 3]

// Define matrix B
var b = [
[3, 1, 3],
[1, 1, 2],

multiplication(a, b);
}
// Start program execution

Output

``````  Matrix A
[ [ 1, 2, 3 ], [ 6, 1, 2 ], [ 5, 4, 3 ] ]
Matrix B
[ [ 3, 1, 3 ], [ 1, 1, 2 ], [ 2, 2, 3 ] ]
Matrix [(A) x (B)]
[ [ 11, 9, 16 ], [ 23, 11, 26 ], [ 25, 15, 32 ] ]``````
