Adding several variables together

Hi: My question is probably very simple to solve but I am having trouble with how to do it: I have three matrices (30x30) saved with the name A_1, A_2, A_3. I would like to add them together so that it gives a new variable (lets call it totalA) which is also 30x30 and has a value in each cell which has been calculated by adding for example row 1,column 1 of A_1,A_2 and A_3 together. I have tried using load and sum (A_1,A_2,A_3) but it gives me some errors. Any help would be appreciated Guillermo

Ummm, am I missing something?

totalA = A_1+A_2+A_3;

Probably not, something very stupid which I forgot...Im sorry and thanks for the help!
