Look and Say Sequence (Morris Sequence)

I am trying to implement the following sequence into Matlab using loops. The sequence is generated as follows:

V1=(1) Because it reads off V1 as "one 1" or "11"

Hence V2=(1,1)

V3=(2,1) Because it reads off V2 as "two ones" or "21"

Hence V4=(1,2,1,1) Because it reads off V3 as "one two one one" or "1211"

The sequence continues indefinitely

How can I write a script to produce this using "for" loops rather than the in-built functions?

Hence the sequence is (1),(1,1),(2,1),(1,2,1,1) and so on...
