> I'm quite sure that there is a possibility to find out, with which Matlab release a certain Matlab function was introduced. I would need this to keep some downward compatibility in my Matlab codes.


There is no facility to know this. I wish there was. So here
is an enhancement idea...

Create a new function, I'll call it "whence", that would indicate
when called what Matlab release any function was introduced.
Thus

  whence convhulln

would return something like the number 11, since I think it
was introduced in release 11.
