finding the average in a matrix

Hi, I have a matrix 62599x60 double. I want the average of the 60 columns in every row. The output should be a 62599x1 matrix.

If you want the sum, use sum() instead of mean().
sumsAcrossColumns = sum(M, 2);
If you want the min or max, it's slightly different in that you need to insert [] before the dimension argument.
minsAcrossColumns = min(M, [], 2);
maxsAcrossColumns = max(M, [], 2);
