VBA - 创建 n × m 矩阵的函数

使用VBA编程语言可以轻松创建n × m矩阵，这是一种非常有用的功能。矩阵是一个二维数组，可以存储和处理大量数据。在本文中，我将介绍如何使用VBA编写一个函数来创建n × m矩阵，并提供一个实际的案例代码来演示其用法。

vba
Function CreateMatrix(n As Integer, m As Integer) As Variant
    Dim matrix() As Variant
    ReDim matrix(1 To n, 1 To m) As Variant
    CreateMatrix = matrix
End Function

vba
Sub TestCreateMatrix()
    Dim matrix() As Variant
    Dim i As Integer, j As Integer
    matrix = CreateMatrix(3, 4)
    For i = 1 To 3
        For j = 1 To 4
            matrix(i, j) = i * j
        Next j
    Next i
    For i = 1 To 3
        For j = 1 To 4
            Debug.Print matrix(i, j)
        Next j
    Next i
End Sub
