Create a vector from repetition of two others

Greetings

I come to you with what should have an easy solution but one that I can't seem to figure out.

I want to make a line vector from two other vector that have the same size by repeating them a number of time alternatively.

For example

A=[1 2 3 4 5];
B=[6 7 8 9 10];
n=20;
C=[A,B,A,B,A,B,......] %n times

Thank you in advance for your help

repmat([A,B],1,n)

Thank you very much, that is the answer I was looking for.

Answer 2

[John D'Errico]

A=[1 2 3 4 5];
B=[6 7 8 9 10];
reshape([A;B],1,[])

ans = 1×10

1 6 2 7 3 8 4 9 5 10

Hello,　thank you for your answer.

The problem with this would be that the two vector change. I would like to keep the order of A and B as they are. The second problem is that they are not repeated a certain number of time.

The one I seek would be [1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3...etc.. ]

Thank you again,
