I want to take 2 ranges, 1 dim each, can be 2 rows or 2 columns, but I need
to take a cell from one range and do something with it's 'parallel' cell in
the other range.
for example, something like a root mean square deviation. One column is
data values, other column is expected values and the loop sums
(data(i)-expect(i))^2...
here is how I understand doing something like this on one column or row,
very simple, no error checking...
Function rms(ByVal Target As Range) As Double
'root mean squared. quadratic mean
Dim Cell As Range
Dim summand As Double
Dim tot As Integer
tot = 0
summand = 0#
For Each Cell In Target.Cells
If IsNumeric(Cell) Then
tot = tot + 1
summand = summand + Cell ^ 2
End If
Next Cell
rms = Math.Sqr(summand / tot)
End Function
what i do not understand or can't figure is how to do tghis kind of thing
on 2 ranges where a cell from one and a similar cell from the other are co
processed. Perhaps using .address or .row or .col mixed and matched or
split out... But is there some simpler way?
thank you
