Hi Everyone,
Suppose I have a matrix A, which has r rows and c columns.
For each of the rows A, I wish to find the mean of the highest n numbers, to create B, which is a 1,c matrix, containing these means.
How can this be done?
Regards
Ulrik

A = sort(Matrix,2,'descend'); %sort it so big numbers first
B = mean(A(:,1:n),2) %mean them
