What is the best practice in MATLAB to increase a variable in a cycling way?

Question

I have some variables that need to be incremented in a loop, and should go back to 0 when hit some value. The current way I am doing this is:

cluster = 1;
for I = 1 : n
  cluster = clusterNumber + 1;
  if cluster == max
    cluster = 1;
  end
end

However, as the script goes on, there are a lot of these cases.

So, is there a function in MATLAB or a better way to do this? For example, writing a function like this:

cycling-increase(count, interval, max, backToValue);

Thanks!

Meanwhile, this is my first question. Please do tell me if anything I put up does not meet the rules or conventions of MATLAB Answers. Thanks again!

Just use mod:

for k = 1:10
    1+mod(k-1,5)
end

which displays:

ans =  1
ans =  2
ans =  3
ans =  4
ans =  5
ans =  1
ans =  2
ans =  3
ans =  4
ans =  5

That is such a genius and elegant solution! Thanks! Really appreciate it!
