vb程序运行时提示下标越界是什么意思

Public Function multi(A() As Double, B() As Double, n As Long, n1 As Long, n2 As Long, c() As Double) As Double Dim T1 As Integer Dim T2 As Integer Dim T3 As Integer For T1 = 1 To n1 For T2 = 1 To n2 For T3 = 1 To n c(T1, T2) = 0 c(T1, T2) = c(T1, T2) + A(T1, T3) * B(T3, T2) Next T3 Next T2 Next T1 End Function

Answer 1

函数看不错错误来，这个得看你调用函数时 n，n1，n2 怎么赋值的
c(T1, T2) = c(T1, T2) + A(T1, T3) * B(T3, T2)
这个语句很可能会导致下标越界 ，特别是 B(T3, T2)
