Brush up Array Operation by example

[frtklau]

Dear all,

I found some examples of using Array operation like
IF(ISNA(MATCH(...
SUMPRODUCT(--(--A1:A100=5))
more advanced of VLOOKUP & Match.
to get interesting things done very efficiently.

I wonder if there's a reference to web page(s) with Excel file as
example so that I can take as tutorial.

thanx for pointing

Frankie.

If you want to read more about =vlookup() and =index(match()), take a look at
Debra Dalgleish's site:
http://www.contextures.com/xlFunctions02.html
http://www.contextures.com/xlFunctions03.html

And Debra has lots of info on counting:

including =sumproduct()
