array sum

[fmg.mdq]

Hi guys!
i having an issue when i tried to sum two arrays.
Example:
Sub suma_arrays()
Dim arr1(1 To 2, 1 To 2) As Variant
Dim arr2(1 To 2, 1 To 2) As Variant
Dim arr3(1 To 2, 1 To 2) As Variant
arr1(1, 1) = 1
arr1(1, 2) = 2
arr1(2, 1) = 3
arr1(2, 2) = 4
arr2(1, 1) = 1
arr2(1, 2) = 2
arr2(2, 1) = 3
arr2(2, 2) = 4
arr3 = arr2+arr1
End Sub
but excel shows me that types didn't match!
Any ideas?

Hi there, welcome!

How exactly do you want to add these? Just add all elements? You have a 2x2 array (two of them), so you'll need to define just exactly what you want to add. With the example shown, what should be the expected results? 20?

ok you are right, i expect to obtain a 2x2 array, i know i can do ti with a for but i want to know if there some excel function to do it faster!
result
arr3(1, 1) = 2
arr3(1, 2) = 4
arr3(2, 1) = 6
arr3(2, 2) = 8

While one could add the elements in a For loop using LBound and Ubound a bit similar to what I did in this For loop, I just used the ArrayAdd() and related routines in the link.
[vba]Sub suma_arrays()
Dim arr1(1 To 2, 1 To 2) As Variant
Dim arr2(1 To 2, 1 To 2) As Variant
Dim arr3() As Variant
arr1(1, 1) = 1
arr1(1, 2) = 2
arr1(2, 1) = 3
arr1(2, 2) = 4
arr2(1, 1) = 1
arr2(1, 2) = 2
arr2(2, 1) = 3
arr2(2, 2) = 4

'Add module from: http://home.pacbell.net/beban/
arr3 = ArrayAdd(arr2, arr1)
Dim i As Integer, j As Integer
For i = 1 To 2
For j = 1 To 2
Debug.Print "arr3(" & i & "," & j & ")", arr3(i, j)
Next j
Next i
End Sub[/vba]

And what of the results? Do you want to keep it in an array? Shall you sum all of the results together? Please explain more.
