I have A=[1 3; 2 4]; and B=[5 6; 7 8];
I would like to create this two matrix line by line in C :
C=[1 3;5 6; 2 4; 7 8];

@marwa hajji did you see my Answer below (scroll down to the official Answers section, not up here in the comments section which is supposed to be used to ask the original poster for clarification)?

A couple different ways:
>> A = [1 3; 2 4]
A =
1 3
2 4
>> B = [5 6; 7 8]
B =
5 6
7 8
>> C = A
C =
1 3
2 4
>> C = [C; B]
C =
1 3
2 4
5 6
7 8
>> C = [A; B]
C =
1 3
2 4
5 6
7 8

This
C =
1 3
2 4
5 6
7 8
is not what he wanted. He said he wants
C=[1 3;5 6; 2 4; 7 8]

Try this:
A=[1 3; 2 4]
B=[5 6; 7 8]
% What is desired:
C = [1 3;5 6; 2 4; 7 8]
% My code
C2 = [A(1,:); B(1, :); A(2,:); B(2,:)]
If you need it generalized to interleave a different number of rows than 2, or if A and B might have different numbers of rows, then it would be more complicated.
