Array Formulas with multiple arguments


Posted by Julie Braford on September 02, 2001 5:14 PM

Is there a limit to the number of arguments that can be used in an array formula? I am not able to get a sum,if & and statment as an array to work. It will accept it with an additional (uneccesary) set of parentheses, but it does not function properly. Here is the exact array formula:

{=sum(if((and(ColumnB<(b$22+b$23),ColumnB>(B$22-B$23))),1,0))}

I am trying to count the number of results within a range that fall within a range (can't use contstant values), is there another way to do?

Thank you for your help.

=SUM(IF((B1:B1000<(B$22+B$23))*(B1:B1000>(B$22-B$23)),1,0))

Notes :
The AND function cannot be used in array formulas. An asterisk is used instead.
Complete column refs cannot be used.

=SUMPRODUCT((B1:B1000<B22+B23)*(B1:B1000>B22-B23))

which is entered normally.

Yep. Neither in SUMPRODUCT. However, there is a way to do just that:

=SUMPRODUCT((Used(B:B)<B22+B23)*(Used(B:B)>B22-B23))

Used is a user-defined function (due to Harlan Grove). It requires that the latter formula must be in the same worksheet as the data of interest.

:
=SUMPRODUCT((B1:B1000 < B22+B23)*(B1:B1000 > B22-B23))

Can you post the UDF code please

Re: Can you post the UDF code please

Anon,

Here it is.

Function Used(r As Range) As Range
'
' Harlan Grove
'
Dim q As Range
Set q = r.Parent.UsedRange.Cells(r.Parent.UsedRange.Cells.Count)
Set Used = Intersect(r, r.Parent.Range(Cells(1, 1), q))
End Function

To be complete:
In order to use this UDF, activate the option Tools|Macro|Visual Basic Editor. Activate Insert|Module. Paste the UDF in the open space on the window which carries the "(code)" bit in the title. Activate File|Close and Return to Microsoft Excel.

Thanks. And of course, the code is so simple when you see it !
