Combine two matrices into one

I have two matrices A and B and i want them to compain into a new matrix. The number of rows for matrices A and B are always 20, and only the number of column can change but it is the same for both( for instance if A is [20x50] then B is also [20x50]).

I want them to combine into a new matrix C so that the first row of matrix C is the first row of matrix A and the second row of matrix C is the first row of matrix B.

For example:

A = [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]
B = [41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60; 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80]

C = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60; 
    21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40; 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80]

Thank you

Hi Mario,

As far as A and B have same sizes, you can perform the following:

C = zeros(2*size(A,1),size(A,2));
C(1:2:end,:) = A;
C(2:2:end,:) = B;

Hope this helps.
