MATLAB: How to fill in this matrix

indexindexinglooploopsmatrix

I have a 3×1536 matrix named time
On the 2nd row I'm trying to fill it in with hours of the day but I need four of each hour so for example:
1 1 1 1 2 2 2 2 3 3 3 3…24 24 24 24 1 1 1 1 2 2 2 2 and so on
.
I have no idea how to go about indexing the matrix in a way that I don't have to write then modify 96 loops/indexing lines of code because I have to fill it out in the only way I can think of right now which is:
for a=1:96:1536
      time(2,a)=0;
end
.
for b=2:96:1536
      time(2,b)=0;
end
...
for e=5:96:1536
      time(2,e)=1;
end

Edit
n=1536/4
c2=repmat(1:n,4,1);
time(2,:)=circshift(mod(c2(:)',24)+1,[0 4])
%or
n=1536/(24*4)
a=repmat(1:24,4,1)
time(2,:)=repmat(a(:)',1,n)
