Dear useRs,
I have a matrix of 120 row and 1000 columns.What I want is to get an average of a set of 12 rows starting from 1 till 120 for each column. Precisely, for column 1 the average of 1:10 rows, 11:20 rows.... 111:120. similarly for column 2, 3, 4.... 1000. So in the end i should have a matrix with 12 rows and 1000 columns.
Thankyou very much in advance.

Eliza
