i have this Matrix, consisting of 3 columns: Column 1: long Column 2: lat Column 3: year
lets say 97x281x15,
I want to make average for each year. so i want the result is 1x15, or 15x1
or kind of look like this
YEAR / DATA AVERAGE
1995 25.786
1996 25.686
1997 25.746
1998 25.686
and so on
Thank you for your suggestions.

If you're matrix has 3 columns, the size should be of size rowX3, can you upload a subset of your data (mat/delimited file)?

In recent Matlab,
mean(SSTmonth,[1,2])
In older Matlab,
mean(reshape(SSTmonth,[],15),1)

Apparently your array is not 97x281x15 because if so there is no way that 15 would not be divisible into the number of elelments.
