How do I create a vector of 20 elements with the numbers 1,2,3,4,5 repeated four times?

It has to look like this [0 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5]
Any suggestions?
Thanks

But the vector you show has 21 elements, not 20. Until you learn to be accurate in your questions, intelligent answers will be difficult to come by.

We find 3 smart answers inspite of the incorrect question. In theory, this is not possible. But in practice, the forum can overcome such limitations. It is interesting where the missing information could come from. I think it is the experience from other questions and own programming projects.
@Krithika Karri: Please use meaning ful tags. All questions in this forum conern "matlab".

You can create a smaller vector of the repeating entries and then repeat this vector with the REPMAT function for 1 row and 4 columns:
smallVector = [1 2 3 4 5];
result = repmat(smallVector,1,4);
If you need to put that 0 at the front, you can then enter:
result = [0 result];
