    So you want a sum of all of that combined? Just add all the numbers in both matrices and multiply by 27.

    do you want to multiply them elementwise and sum the products? Be more clear with what you want to do.

    also post what you've tried so far.

    Finally,i found the solution of this problem::)

    for ii = 27:-1:1
    for jj = 27:-1:1
    Result(:,jj+(ii-1)*27) = A(:,ii) + B(:,jj);
    end
    end
