Actually I was referring to using the class from an .oct file not from an .m file ... anyway yes you can construct a new class in c++ and have it accessible in the interpreter an be persistent between calls. In order to do this your class must inherit from the octave_base_value class. > This is not possible with plain mex files in Matlab because you must create > an instance of a C++ class which will be destroyed once the mex file > completes (which is the problem that using handle classes in the linked > example solves).

The instrument control package is a working example of how this can be done, for a much simpler example you can have a look at these files: http://inversethought.com/hg/what-is-octave/file/f8c352d9af2d/PoliMI2012/examples/myobject.h http://inversethought.com/hg/what-is-octave/file/f8c352d9af2d/PoliMI2012/examples/myobject.cc which are examples taken from this presentation http://jordi.platinum.linux.pl/octave/what-is-octave.pdf > Richard c. ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
