How to determine maximum of n times FOR loop iteration

Dear all, This may sound so basic, but I had google using various keyword (or maybe I used wrong keyword), but I failed to find good info on how to calculate how many cycle the FOR loop iterate.

For example

% the following FOR loop will iterate max 3 times
  for i =0.1:0.3:0.9
      a =i
  end

AND

% the following FOR loop will iterate max 4 times
  for i =0.1:0.3:1
      a =i
  end

In the above case, I manually check the the first and second FOR loop will cycle 3 & 4 time, respectively. My question is, is there way I can calculate it automatically?

Thanks in advance

The only way to know in advance the number of iterations a loop can take is to specify them as a separate variable and see the number of elements in it:

v1 = 0.1:0.3:0.9;
iter1 = numel(v1)
for i = v1
    a =i
end

iter1 =
     3

a =
          0.1

a =
          0.4

a =
          0.7
