how to calculate max and mean for big matrix 10*155 but i need to pick the value after coloumn 50?

Do i need to create a new matrix and input all value from col 50 to 155? or i can do it in some other ways but not to make new matrix?

Benjamin, use

 max_mat  = max(mat(:,51:end),[],2)
 mean_mat = mean(mat(:,51:end),2)

assuming you want to compute max and mean for each row.
