0 -1 12 5;
1 13 -15 7;
6 -8 0 -5]
Z = zeros(3,4)
E = [B;Z]
M = Transpose(E)*E %Assigne product of E transpose and E to M
disp( M(2,3)) %get 2nd row , 3rd col of M
output
B = -8 15 4 -11 3 5 6 -2 0 -1 12 5 1 13 -15 7 6 -8 0 -5 Z = 0 0 0 0 0 0 0 0 0 0 0 0 E = -8 15 4 -11 3 5 6 -2 0 -1 12 5 1 13 -15 7 6 -8 0 -5 0 0 0 0 0 0 0 0 0 0 0 0 M = 110 -140 -29 59 -140 484 -117 -49 -29 -117 421 -101 59 -49 -101 224 -117
