Array multiplication in VBA
Just as a point of interest, in light testing using the arrays provided, the
method suggested by Dana is more than 200 times slower than looping through
the arrays and doing the multiplication. Using MMULT was 10 times slower.

Dan. This is not the best, but it's the only non-looping way I know of.

Sub Demo()
'//Dana DeLouis
Dim v, w, z
v = Array(1, 2, 3, 4)
w = Array(10, 11, 12, 13)
ActiveWorkbook.Names.Add "t_", Array(v, w)
z = [Index(t_,1,0)*Index(t_,2,0)]
End Sub

I am trying to simulate the behaviour of an array multiplication such as
{=(A1:A10)*(B1:B10)} in VBA. The resulting array should contain:
={A1*B1, A2*B2, . . . , A10*B10}.
I was hoping to avoid writing a loop if it is at all possible?
I don't think there is a worksheetfunction which does this and I was
hoping to avoid the loop:
For i = 0 to Ubound(Temp1)
Temp3(i) = Temp1(i)*Temp2(i)
Next
Is there an easy way to do this?
