Thread Subject: Finding which Matlab version introduced a function

Hi,
I'm currently trying to make some of my code (written for Matlab
R2009A) work on an older version (R14 / 7.0.4).

Because it's a while since I used the code, sometimes it's unclear if
I don't have functions on the path (which I can quickly solve with
"which") or if new functions have been added to Matlab. One particular
example is "setallowaxeszoom". As far as I can tell, it was added
between 2007 and 2009.

I've also found that "isfield" now accepts cell arrays as inputs,
whereas previously it only accepted single strings.

So, my specific question: is there any way that I can find out when
features were added to existing functions, or when new functions were
added? This will help me develop work-arounds.

Here's some pages that may help you. It seems you're not the first person who has wanted to know this.

Another couple of blogs gave abbreviated lists of some of the changes to Matlab, mostly related to image processing

and to the Image Processing Toolbox directly
