Follow-up Comment #2, bug #54096 (project octave):

The end of the post disappeared here because of a botched verbatim tag.

Anyway, I think you mean a NULL argument to mxSetFieldByNumber?

I'm pretty sure that mxCreateDoubleMatrix (0, 0, mxREAL) does not return NULL.
 But maybe Matlab handles NULL specially in this case?

Regardless, we should definitely not be creating invalid objects.

However, I'm curious to know whether it is documented that Matlab accepts NULL
here to mean "empty matrix".
