Go 矩阵乘法程序

在此 Go 矩阵乘法程序中，我们使用了两个 for 循环。第一个 for 循环执行矩阵乘法并将值赋给乘法矩阵。第二个 for 循环打印该矩阵中的项。

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()
    }
}

Enter the Multiplication Matrix Rows and Columns = 2 2
Enter the First Matrix Items to Multiplication = 
10 20
30 40
Enter the Second Matrix Items to Multiplication = 
3 4
5 6
The Go Result of Matrix Multiplication = 
30      80
150     240

Go 程序示例：两个矩阵相乘

在此 示例中，我们使用 for 循环 range 将值赋给 multimat1 和 multimat2。接下来，我们使用另一个 for 循环执行矩阵乘法并打印结果。您也可以使用另一个 for 循环来打印矩阵项。

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()
    }
}
