How can I combine 2 matrices A and B into one so that the new matrix C = element 1 of A, followed by element 1 of B, then element 2 of A, element 2 of B, etc? Note that vectors A and B are randomly generated and the size might be different.
For example, A = [x1 x2 x3 ...], B = [y1 y2 y3 ...] and then C=[x1 y1 x2 y2 x3 y3 ...]
Thank you.

A=1:3
B=4:6
C=[A;B]
C=C(:)'
%or
C=reshape([A;B],1,[])

Thank you Azzi so much for your help and quick response. this (C=reshape([A;B],1,[])) works perfectly.
Thanks again, Khalid

Hi! I'm looking for a simmilar thing. How would this vork with more than two vectors arranged in a matrix? For example:
a = [1 2 3];
b = [4 5 6];
c = [7 8 9];
d = [10 11 12];
And it should result in:
res =
1 4 2 5 3 6
7 10 8 11 9 12
Which is:
res =
a(1) b(1) a(2) b(2) a(3) b(3)
c(1) d(1) c(2) d(2) c(3) d(3)
