Say
for some
. How can I create an array of size
which is just
i.e repeat the elements of x M times each in a row.




Note I have tried using the reshape function but cant work out how to do it in this case.

What have you done so far? What specific problems are you having with your code?

repelem is good for repeating an element n times, so I think this is what you want. Here I repeat the numbers in a 3 times each:
a=[1 3 7 9];
repelem(a,3)
repmat is good when you want to repeat an array of elements, here I repeat a itself 3 times in the row dimension, and 2 times in the column dimension:
repmat(a,3,2)
