Generate a vector like [5,4,4,3,3​,3,2,2,2,2​,1,1,1,1,1​]

How can I generate a vector like [5,4,4,3,3,3,2,2,2,2,1,1,1,1,1] without a loop?

repelem() can do it with a single call.

I will not show the code because this appears to be homework.

Currently I am using the following code:

odds = reshape(triu(repmat(5:-1:1,5,1)),1,[]);

odds(odds==0) = [];

I don't know if this is the better way to do or is better a loop. Thanks for your help.

It's overly complicated. You only need one call to repelem with two (trivial) vectors as inputs. I don't see the point in creating a matrix.

I have used this code: odds = repelem([5,4,3,2,1],[1:5]);

It's just what I was looking for. Thank you.

The square brackets are unnecessary.

odds = repelem(5:-1:1, 1:5)
