What you have will call f from inside f (which is called "recursion")
However, your code does not have any protections for the case that "m" is odd, and does not have any way to stop iterating when you get down to m == 1.

Just as a side issue: You better change the name of the function from a one letter name "f" to at least a 2 letter name. I remember I was trying to compute function of a function and MATLAB has issues (bugs) in calculating the result..(not sure if it's already fixed or not)... but things like sin(f(2)) or g(f(x)) may fail for a generic f function even if f is correctly defined.
This has nothing to do with the "recursion" Walter is talking about.

I have not heard of any issue with single-letter names. Do you have the bug report number, or a link to where you have posted about this before?
