Posting a representative sample of your data might help.
What do want? The days it rained more than 0.1 mm but less than 2.5 mm, etc., only the days it rained at least 244.5 mm, or something else?

Please reply to each of us and don't post "Answers" of your own that are not actually "Answers" to your original question. Star Strider has asked twice now for sample data. Post that, along with code to read it in from a file if you're attaching a data file, and tell us what value, and what location it's in, that you would like to extract from it.

You mean an example like this:
format short g
% Create sample data: Rainfall for 10 years.
% An array 10 years tall by 12 months wide
rainfall = 9*rand(10, 12)
% Get rainiest year for each month.
[maxRain, yearOfMax] = max(rainfall)

By my calculations, you have one page (3rd dimension) for every day. It might help for you to post one (20x22) page and explain what you want to get from it.
