I have a vector of numbers. i.e [ 1 2 3 4] I want to repeat that specific vector a certain number of times, to make a matrix of x rows. It's just the first row repeating itself x times. So it would be [ 1 2 3 4; 1 2 3 4; 1 2 3 4] If x was 3. However I cannot use repmat nor use an iteration

Hi,
This can be also done using the REPELEM command as follows:
v = [1:4];
repelem(v,[3],[1])
Follow the link below to know more about this function:

@sam0037Could you please explain how the second and third arguments in your function work?
The documentation doesn't provide an example of what happens when you put one-dimensional vectors as arguments to repelem.

They don't have to be vectors, simple ints accomplish the same goal. Not sure why they are bracketed in that example.
