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.
Thank you for any hint.

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.

Funny, I was just searching for this exact functionality. If John says it doesn't exist, it probably does not, which is too bad. Surely it could rely on mlint like crawling through the code to figure out what is and is not compatible. Further suggestions for ensuring compatibility through a certain version would also be useful.
A friendly bump for Steven or other fine Mathworks folks to respond?
Thanks.

The text "Mastering MATLAB 7" has an appendix that contains this information as obtained by reviewing all the release notes back to MATLAB 5, R10.

I suggest using the EXIST function to determine whether or not the function you're looking for exists in the MATLAB installation you're running under. If it doesn't, then switch to an alternate algorithm.
See
>> help exist
to see how to use the EXIST function to determine whether or not a function exists.
Hope that helps,
