hello , anyone kindly help me, i have a 91by91 matrix (A) generated in a loop of 140 . i want to add all the matrices in the various together into a final one which is also a 91by91. Thanks

for i=1:length(data(:,1)) %%i is 140 
     A=sqrt(C.^2 + S.^2);
     [L_max,M_max] = size(A); %%L_max,M_max =90
    T_sum(i,1:M_max)=sum(A);
end

Try this

for i=1:length(data(:,1)) %%i is 140 
    A=sqrt(C.^2 + S.^2); % or whatever....
    if i == 1
        T_sum = A;
    else
        T_sum = T_sum + A;
    end
end
