Combining multiple rows from one matrix to another matrix

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?

Use the reshape function —

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];

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

Q = 5x10

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

% 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:');

Matrix Q:

disp(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
