I.e. if I want to make a list 400 values long of all 1's, I would use
ones(400,1)
But what if I wanted to make a list of say, 5's?
Is there a function I can use to do this without using a for loop?

Try this —
Fives = 5*ones(400,1)
Fives = 400×1
5 5 5 5 5 5 5 5 5 5
.

Thank you!
I’m certain you would have in a few minutes. (I’ve been doing this for a while.)
Another option —
Fives = 5+zeros(400,1)
Fives = 400×1
5 5 5 5 5 5 5 5 5 5
.
