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.
