Go Program to Find Matrix Determinant

This Go program finds the determinant of the 2 * 2 matrix. First, it allows to enter the matrix items and then uses the math formula to find the matrix determinant.

package main

import "fmt"

func main() {
    var i, j int

    var deterMat [2][2]int

    fmt.Print("Enter the Matrix Items to find the Determinant = ")
    for i = 0; i < 2; i++ {
        for j = 0; j < 2; j++ {
            fmt.Scan(&deterMat[i][j])
        }
    }

    determinant := (deterMat[0][0] * deterMat[1][1]) - (deterMat[0][1] * deterMat[1][0])
    fmt.Println("The Determinant of the 2 * 2 Matrix  = ", determinant)
}

Enter the Matrix Items to find the Determinant = 
10 25
19 50
The Determinant of the 2 * 2 Matrix  =  25

This Golang program calculates the 3 * 3 matrix determinant.

package main

import "fmt"

func main() {
    var i, j int

    var deterMat [3][3]int

    fmt.Print("Enter the Matrix Items to find the Determinant = ")
    for i = 0; i < 3; i++ {
        for j = 0; j < 3; j++ {
            fmt.Scan(&deterMat[i][j])
        }
    }

    x := (deterMat[1][1] * deterMat[2][2]) - (deterMat[2][1] * deterMat[1][2])
    y := (deterMat[1][0] * deterMat[2][2]) - (deterMat[2][0] * deterMat[1][2])
    z := (deterMat[1][0] * deterMat[2][1]) - (deterMat[2][0] * deterMat[1][1])

    determinant := (deterMat[0][0] * x) - (deterMat[0][1] * y) + (deterMat[0][2] * z)
    fmt.Println("The Determinant of the 3 * 3 Matrix  = ", determinant)
}
