Do you means, you want the sum of all the values for a given matrix (for example, (7 8 9;2 1 4; 5 6 3)) ?

"May the question is: how to sum a 9 matrices elements in a for loop?"
No need of loop, here mat is given matrix
result=sum(mat(:))
Must be loop have to use, then,
Hints:
for i=1:r
for j=1:col
sum_mat=sum_mat+mat(i,j);
end
end

Then Hints are sufficient, I will not tell you more. Please read Matlab documentation.
