Let's say I have a vector a that is of size 4. I have a vector b of size 10. I want to copy the contents of vector a into b until it 'runs out'.
For example: if a = [1 2 3 4]; and b is a size 10 vector.
Then b = [1 2 3 4 1 2 3 4 1 2].
How do i do this?

Ran in:
a = [1 2 3 4];
b = a(mod(0:9, 4)+1)
b = 1×10
1 2 3 4 1 2 3 4 1 2
