VB 控制台程序实现矩阵加法、转置和乘法运算（无 Dim 语句）

在 VB 中，使用控制台程序编写代码可以实现矩阵加法、转置和乘法运算。下面是一个示例代码，使用数组来代替'Dim'语句：

Imports System

Module Program
    Sub Main(args As String())
        ' 定义矩阵 A
        Dim A(,) As Integer = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}

        ' 定义矩阵 B
        Dim B(,) As Integer = {{9, 8, 7}, {6, 5, 4}, {3, 2, 1}}

        ' 打印矩阵 A
        Console.WriteLine('矩阵 A:')
        PrintMatrix(A)

        ' 打印矩阵 B
        Console.WriteLine('矩阵 B:')
        PrintMatrix(B)

        ' 计算矩阵加法
        Dim C(,) As Integer = MatrixAddition(A, B)
        Console.WriteLine('矩阵加法结果:')
        PrintMatrix(C)

        ' 计算矩阵转置
        Dim D(,) As Integer = MatrixTranspose(A)
        Console.WriteLine('矩阵 A 的转置:')
        PrintMatrix(D)

        ' 计算矩阵乘法
        Dim E(,) As Integer = MatrixMultiplication(A, B)
        Console.WriteLine('矩阵乘法结果:')
        PrintMatrix(E)

        Console.ReadLine()
    End Sub

    ' 打印矩阵
    Sub PrintMatrix(matrix As Integer(,,))
        Dim rows As Integer = matrix.GetLength(0)
        Dim cols As Integer = matrix.GetLength(1)

        For i As Integer = 0 To rows - 1
            For j As Integer = 0 To cols - 1
                Console.Write(matrix(i, j) & " ")
            Next
            Console.WriteLine()
        Next
        Console.WriteLine()
    End Sub

    ' 矩阵加法
    Function MatrixAddition(matrix1 As Integer(,), matrix2 As Integer(,)) As Integer(,,)
        Dim rows As Integer = matrix1.GetLength(0)
        Dim cols As Integer = matrix1.GetLength(1)

        Dim result(rows - 1, cols - 1) As Integer

        For i As Integer = 0 To rows - 1
            For j As Integer = 0 To cols - 1
                result(i, j) = matrix1(i, j) + matrix2(i, j)
            Next
        Next

        Return result
    End Function

    ' 矩阵转置
    Function MatrixTranspose(matrix As Integer(,)) As Integer(,,)
        Dim rows As Integer = matrix.GetLength(0)
        Dim cols As Integer = matrix.GetLength(1)

        Dim result(cols - 1, rows - 1) As Integer

        For i As Integer = 0 To rows - 1
            For j As Integer = 0 To cols - 1
                result(j, i) = matrix(i, j)
            Next
        Next

        Return result
    End Function

    ' 矩阵乘法
    Function MatrixMultiplication(matrix1 As Integer(,), matrix2 As Integer(,)) As Integer(,,)
        Dim rows1 As Integer = matrix1.GetLength(0)
        Dim cols1 As Integer = matrix1.GetLength(1)
        Dim cols2 As Integer = matrix2.GetLength(1)

        Dim result(rows1 - 1, cols2 - 1) As Integer

        For i As Integer = 0 To rows1 - 1
            For j As Integer = 0 To cols2 - 1
                For k As Integer = 0 To cols1 - 1
                    result(i, j) += matrix1(i, k) * matrix2(k, j)
                Next
            Next
        Next

        Return result
    End Function
End Module

这个代码示例中，我们使用了一个 PrintMatrix 函数来打印矩阵，这个函数接受一个二维数组作为参数，并根据数组的大小打印矩阵的元素。

我们还定义了 MatrixAddition 函数来计算矩阵的加法，MatrixTranspose 函数来计算矩阵的转置，以及 MatrixMultiplication 函数来计算矩阵的乘法。这些函数都接受两个二维数组作为参数，并返回一个新的二维数组作为结果。

在 Main 函数中，我们定义了两个矩阵 A 和 B，并打印它们的内容。然后，我们分别调用了 MatrixAddition、MatrixTranspose 和 MatrixMultiplication 函数来计算矩阵的加法、转置和乘法，并打印结果。

最后，我们使用 Console.ReadLine() 来等待用户按下回车键，以保持控制台窗口打开，直到用户关闭程序。
