Details:

The same happens for meta.package.fromName. 
For Matlab these functions simply return an empty (0x0) class array or package
array. I wrote a simple patch that returns just an empty object ([](0x0))
instead. The functionality is already built-into Octave in the functions:
cdef_manager::find_class
<http://hg.savannah.gnu.org/hgweb/octave/file/1909078be6c7/libinterp/octave-value/ov-classdef.h#l1618>
cdef_manager::find_package
<http://hg.savannah.gnu.org/hgweb/octave/file/1909078be6c7/libinterp/octave-value/ov-classdef.h#l1624>.

The only change I made was to call them with the proper argument:
error_if_not_found == false.

I am attaching a patch in to this submission.
