Repeat vector n times

I have a vector t_vec. I want to create another vector that is the repetition of t_vec n types, so that is shows somehting like this: [ion, ion, off, off, off, ion+randn, ion+randn, ioff, ioff, ioff,...], with a different value for randn each time

ton=2;
toff=3;
ion=0.7;
ioff=-6;
t_vec1(1:ton)=ion+randn;
t_vec1(ton+1:ton+toff)=ioff;

How do I do this?

Have you tried repmat, say

n = 2;
t_vec = [ion ion ioff ioff ioff];
repmat(t_vec,1,n)
