i tried zeros command and defined a function for summation but i already used 3 commands for do this. I am trying to do this with multiplication and summation but again i am using 3 commands. I think i cant do that with multiplication etc.

Check if this works.

E=zeros(5,5);
E(3:5,3:5)=[1,2,3;4,5,6;7,8,9]

E = 5×5

0 0 0 0 0 0 0 0 0 0 0 0 1 2 3 0 0 4 5 6 0 0 7 8 9
