How to deal with for loop

I want to ask about for loop. I have 50 matrices of Z and I want to use for loop to add them and take the average of these Z matrices.

Answer 1

N_matrices = 50;                     % number of matrices 
total = zeros( size(Z(1) );          % initialization of total addition 
for k = 1:N_matrices                 % loop over all the matrices 
total = total + Z(k);                % update the addition 
end                                  % end the loop

Answer 2

[David Sanchez]

N_matrices = 50; % number of matrices total = zeros( size(Z(1) ); % initialization of total addition for k = 1:N_matrices % loop over all the matrices total = total + Z(k); % update the addition end % end the loop
