MATLAB: Mean across rows and columns

mean

i have a code that produces 10 x 5 matrix, i want it to find the mean across the rows rather than down each column.

for a=(1:5);
% some code here
Major1=(MJ_V11);%(0:end); %10 x 5 matrix here
Major11 = mean(Major1);
end

mean(Major1, 2)

The row means would be calculated as the mean of dimension 2.

Try this:

A = rand(5);
Anew = A - mean(A,2);
Check = mean(Anew,2)                    % Confirm: Mean = 0

What is the loop for? It's not needed. Just do this:

Major11 = mean(MJ_V11,2);

If MJ_V11 changes inside the loop, then you can still have it in the loop:

for a = 1 : 5  % No() or ; needed
  MJ_V11 = whatever.....
  Major11(a) = mean(MJ_V11(a,:),2);
end

Note how I added an index to Major11 so that it doesn't get overwritten every time.
