I want to change the size of T so I can Add it to P2 (the size of T should be the size of P1 or the size of P2)

P1=[3 2 4;2 1 1;5 2 3;2 3 7]

P2=[2 6 1;1 3 5;4 2 1;5 2 1];

P1_Zero=pinv(P1)

T=P1_Zero*P1

Q=P2+T

P1=[3 2 4;2 1 1;5 2 3;2 3 7];
P2=[2 6 1;1 3 5;4 2 1;5 2 1];
P1_Zero=pinv(P1);
T=P1_Zero*P1;

% create a new matrix of dimension equal to max(T,P2)
C = zeros(max(size(T), size(P2)))

C = 4×3

0 0 0 0 0 0 0 0 0 0 0 0

% Make C(size(T)) = T. rest = zero
C(1:size(T, 1), 1:size(T, 2)) = T

C = 4×3

1.0000 0 0.0000 0.0000 1.0000 -0.0000 -0.0000 -0.0000 1.0000 0 0 0

% Add both EQUAL matrices now
C = C + P2

C = 4×3

3.0000 6.0000 1.0000 1.0000 4.0000 5.0000 4.0000 2.0000 2.0000 5.0000 2.0000 1.0000
