[...] 2. This is probably a very well thought out solution and easier in terms of operational complexity but requires more work in terms of code. It’s best read directly at Dick Kusleika’s blog – http://www.dailydoseofexcel.com/archives/2004/04/05/anatomy-of-an-array-formula/. [...]

I haven't had a close look at what you have written but think I use pivot tables to obtain similar results. I do have a complex problem, however, and wondered if you might suggest if arrays could be a way of solving it.

If there is a lottery in which 7 winning numbers and 2 supplementary numbers are drawn from 45 numbers, given these numbers and 8 "chosen" numbers, what are all the unique combinations of 7 possible (there should be 8)? In addition, what is the highest combination on winning and supplementary numbers for each unique combination?

Further again, what if we want to look at 9 "chosen" numbers (a system "9?) or 10 (a system "10?)? Can we use Excel arrays to extract this information?

… that should be F9, of course.

It's worth pointing out that if you want to evaluate parts of a formula as Dick has done e.g. convert

D2:D9

into the array of values

{1;1;2;2;2;3;3;3}

simply highlight the relevant part and press F5. Don't forgot to press escape (or equivalent) when done or the evaluated text will remain in the formula.

I have not thought about this before.
They will give the same answer.

ABCD
1ExcelWordPPT
2Apple123
3Orange456
4Kiwi789
5
6Orange
7Word

Normal:
=INDEX(B2:D4;
MATCH(A6;A2:A4;0);
MATCH(A7;B1:D1;0))

Array formula:
{=SUM(
(A2:A4=A6)*
(B1:D1=A7)*
(B2:D4))}

Hey Dick, don't forget MVP Bob Umlas' white paper on array formulas:

Thanks for a nice blog! I enjoy the down to earth style.

Maybe your readers will enjoy my article 'Ignorance - an excellence starting point for learning' where array formulas play a leading role. It is at http://mumnet.tripod.com/thoughts/ignorance.htm.
