How to know starting which MATLAB release a particular function was implemented?

Is it possible to know which MATLAB release has introduced a particular function?
For instance R2013b warns about "quad" suggesting to replace it with "integral" - how can I find when the "integral" was implemented? There's no such info in help/doc. Most of the time the file with the function contains copyright (e.g. "Copyright 2007-2011 The MathWorks, Inc.") - does the first year correspond to the year of release?

Apparently, copyright line does not correspond to the date of release. In this case of "integral" with "copyright 2007-2011" even the R2011b does not have it.

Unfortunately there is no easy way. You can go back through the release notes version by version until you find that it was introduced. See this answer of mine.
I would suggest filing it as an enhancement request with TMW.

INTEGRAL was added in R2012a along with INTEGRAL2 and INTEGRAL3.
