Go Matrix Multiplication Program

In this Go matrix multiplication program, we used two for loops. The first for loop performs the matrix multiplication and assigns the values to the multiplication matrix. The second for loop prints the items in that matrix.

package main

import "fmt"

func main() {
    var rows, columns, i, j int

    var multimat1 [10][10]int
    var multimat2 [10][10]int
    var multiplicationnmat [10][10]int

    fmt.Print("Enter the Multiplication Matrix Rows and Columns = ")
    fmt.Scan(&rows, &columns)

    fmt.Print("Enter the First Matrix Items to Multiplication = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&multimat1[i][j])
        }
    }

    fmt.Print("Enter the Second Matrix Items to Multiplication = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&multimat2[i][j])
        }
    }

    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            multiplicationnmat[i][j] = multimat1[i][j] * multimat2[i][j]
        }
    }
    fmt.Println("The Go Result of Matrix Multiplication = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Print(multiplicationnmat[i][j], "\t")
        }
        fmt.Println()
    }
}

Go Program to Multiply Two Matrices Example

In this Golang example, we used the for loop range to assign values to multimat1 and multimat2. Next, we used another one to perform matrix multiplication and print the same. You can also use another for loop to print the matrix items.

package main

import "fmt"

func main() {

    var multimat1 [2][3]int
    var multimat2 [2][3]int
    var multiplicationnmat [2][3]int

    fmt.Print("Enter the First Matrix Items to Multiplication = ")
    for k, r := range multimat1 {
        for l := range r {
            fmt.Scan(&multimat1[k][l])
        }
    }

    fmt.Print("Enter the Second Matrix Items to Multiplication = ")
    for m, rr := range multimat2 {
        for n := range rr {
            fmt.Scan(&multimat2[m][n])
        }
    }

    fmt.Println("The Go Result of Matrix Multiplication = ")
    for i, row := range multiplicationnmat {
        for j := range row {
            multiplicationnmat[i][j] = multimat1[i][j] * multimat2[i][j]
            fmt.Print(multiplicationnmat[i][j], "\t")
        }
        fmt.Println()
    }
}
