I tested the new mxSetProperty function and it works correctly.

I pushed an implementation of mxSetProperty here:


This changeset also moves the real work of getting/setting properties to the octave_value classdef classes.

mxGetProperty was added recently (http://hg.savannah.gnu.org/hgweb/octave/rev/bd9e719f04cc). Re-titling bug report to list remaining two missing functions.

I've been reviewing and improving the MEX interface for the 4.2 release, and it's in a lot better position now. I filed this bug report mostly as a placeholder because I found these functions missing during the work I was doing. Given that the 4.2 release is imminent, I don't think we need to include a temporary solution. These functions can be part of 4.4 release with plenty of time to get it done right.

I actually don't need it and wrote it following Rik's bug report. I understand it is probably not the right approach and there is a lower level implementation using Octave API directly.

If that does what you want, then I suppose it might be OK as a temporary solution but I don't think it's the right thing to att to core Octave.

What about something like this for mxGetProperty?

The following three functions are missing from Octave's MEX language interface:

Whether it is important, I can't say. But to be complete it should have these functions.
