Re: A question on Matlab compatibility

[A. Scottedward Hodel]

Because sysmult and the rest of the octave controls toolbox was  
written a year or more before MATLAB came out with object-oriented  
functionality in its controls toolbox.  Of course, that was over 10  
years ago.  Bear in mind that MATLAB's controls functions make  
extensive use of MATLAB's user-defined objects, so it would be a  
significant effort to make octave's toolbox behave identically to  
MATLAB's.
