求VB解答.编写程序,实现矩阵转置,即将一个nⅹm的矩阵的行和列互换.

Private Sub Command1_Click()
Randomize Timer
Dim n As Integer,m As Integer
Dim arr1() As Integer,arr2() As Integer
Dim i As Integer,j As Integer
n = InputBox("请输入矩阵的行数")
m = InputBox("请输入矩阵的列数")
ReDim arr1(1 To n,1 To m),arr2(1 To m,1 To n)
For i = 1 To n
For j = 1 To m
arr1(i,j) = Int(Rnd * 10)
Print arr1(i,j);
Next
Print
Next
For i = 1 To m
For j = 1 To n
arr2(i,j) = arr1(j,i)
Print arr2(i,j);
Next
Print
Next
End Su
