Create a for loop with two changing variables

I want to create a loop with 2 variables that change value every loop.

Currently I have:

for nF = [31 30 33 32 18 21 19 20 23 25 22 24 26 27 28 29];

but I would also like a variable 'i' to count from 1 to 16 (count each loop).

Thanks.

nfvals = [31 30 33 32 18 21 19 20 23 25 22 24 26 27 28 29];
for i = 1 : length(nfvals)
  nf = nfvals(i);
  ...
end
