Thread Subject: Object Oriented Changes in 2008a

Can anyone point me to a list of the specific changes
between 2007b and 2008a with regard to support for object
oriented code?

I written some MATLAB code using 2008a that takes advantage
of the latest object oriented features and I just
discovered it also need to run in 2007b and I'm see initial
errors calling a static method on one of my classes but I
can't find a good description of what will / will not work
in 2007.

Thank you.

The answer is simple: there is no object-oriented feature in
2007b.

You might start with the 2008a release notes. They contain
info on the added OOP features.

It's curious that the 2008a release notes indicate
an "update to object-oriented programming capabilities".
There is a clear implication that something existed in the
previous version.

Yes, MATLAB has had some OOP capability for awhile.
User-defined classes, operator & function overloading, etc.

Huh? We've had custom objects in Matlab since version 5.0 in 1997. In
2008a Mathworks released a new object-oriented capability that expands
what used to be possible. All of the old object code continues to work
without changes.

To answer the OP's question, I have not investigated in detail, but I
think the R2008a release notes would be the best place to start.

If this is the case, I stand corrected.

The OO features in 2008a (v7.6) are quite different
from those introduced in v5.0 (which continue to work, but
use a different syntax). I too have found
that code that uses the new features also
mostly works in 2007b but not 2007a. I suspect Mathworks
has been gradually adding more features 'under the hood',
before they officially released it in 2008a.
The main feature I found missing in 2007b was the 'hidden'
attribute, but I'm sure there are many other
incompatibilities...
