vba - 如何将变体传递给双数组 VBA？

Question

我的想法是创建一个函数来传递这样的双数组:

Function pass(a() As Double, b() as double) As Boolean
Dim i As Integer, j As Integer
ReDim a(0 To UBound(b, 1), 0 To UBound(b, 2))
    For i = 0 To UBound(a, 1)
        For j = 0 To UBound(a, 2)
            a(i, j) = b(i, j)
        Next
    Next
End Function

这样人们就可以使用:

pass(a,b)

然后a = b。

a=b

不起作用..(哦，天哪，我想念matlab ..)

好的，回到问题:

这适用于两个双数组，但如果我得到一个变体，并且当我使用它时，我可以获得一个变体，这不起作用。那么有没有将变量值传递给双数组的解决方案？数据的结构类似于 double 数组，但没有 double() 类型。

Answer 1

为了解决这个问题，我将删除参数的类型。

Sub test()

Dim VarArry(0 To 4, 0 To 4) As Variant
Dim DblArry(0 To 4, 0 To 4) As Double
Dim VarAssing() As Variant
Dim DblAssing() As Double
Dim c As Boolean

VarArry(0, 1) = 34
DblArry(0, 1) = 34

c = pass(VarAssing, VarArry)
Debug.Print (TypeName(VarAssing))
Debug.Print (VarAssing(0, 1))

c = pass(VarAssing, DblArry)
Debug.Print (TypeName(VarAssing))
Debug.Print (VarAssing(0, 1))

c = pass(DblAssing, VarArry)
Debug.Print (TypeName(DblAssing))
Debug.Print (VarAssing(0, 1))

c = pass(DblAssing, DblArry)
Debug.Print (TypeName(DblAssing))
Debug.Print (VarAssing(0, 1))


End Sub

Function pass(a, b) As Boolean
Dim i As Integer, j As Integer
ReDim a(0 To UBound(b, 1), 0 To UBound(b, 2))
    For i = 0 To UBound(a, 1)
        For j = 0 To UBound(a, 2)
            a(i, j) = b(i, j)
        Next
    Next
End Function

输出如下

Variant()
 34 
Variant()
 34 
Double()
 34 
Double()
 34
