The multiply method

The multiply method multiplies the elements of two 2 x 2 matrices. The multiplication of two matrices, matrix1 and matrix2, is shown in the following snippet. The matrix that's generated after the multiplication is returned by the multiply method:

// multiply methodfunc multiply(matrix1 [2][2]int, matrix2 [2][2]int) [2][2]int {     var m int    var l int    var n int    var product [2][2]int    for l = 0; l < 2; l++ {        for m=0; m <2; m++ {            var productSum int = 0            for n=0; n< 2; n++ {                productSum = productSum + matrix1[l][n]*matrix2[n][m]            }            product[l][m] = productSum;        }    }    return product}

The product of two matrices is calculated using the multiply method in the following code snippet, which takes the two matrices as parameters:

var product ...
