I have used accumarray before... but thought it just summed the data of interest (i.e. accumulate). Can it be used to find basic stats, too? Yes, just pass a function handle that accomplishes whatever stat you need. Bruno

I need to find some basic stats on the data for each month. I've tried tinkering with codes I've written previously using things like 'find' and 'ismember' functions, but I can't seem to get to the bottom of it. I can easily make a matrix that is the unique year/month combination but can't seem to link these to the actual data to get the basic stats. Any advice? > > Thanks, > Ryan Back on 29 Oct you asked the same question. What was wrong with the suggestions given you back then? Have you actually tried them?

I had the same problem. I posted a code a few days ago.
