Hi..I have a P matrix like this:
Hi,
Let's say I have a P matrix (10*5) and I want to get Q matrix (5*10) from this P matrix where
first two rows of P matrix will be the first row of Q;
rows 3 and 4 of P will be the 2nd row of Q;
rows 5 and 6 will be the 3rd row of Q;
and so on so forth.
Original P matrix is:
P=[1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
26 27 28 29 30
31 32 33 34 35
36 37 38 39 40
41 42 43 44 45
46 47 48 49 50];
I want to get following Q matrix:
Q=[1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50];
Can anyone please help how to get this Q from P?

Q = reshape(P.', 2*size(P,2), []).'

% Define the original matrix P
P = [1 2 3 4 5;
6 7 8 9 10;
11 12 13 14 15;
16 17 18 19 20;
21 22 23 24 25;
26 27 28 29 30;
31 32 33 34 35;
36 37 38 39 40;
41 42 43 44 45;
46 47 48 49 50];
% Reshape P into Q
Q = reshape(P', [10, 5])'; % Transpose P, reshape it, and then transpose the result back
% Display the result
disp('Matrix Q:');
disp(Q);
