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.

Hi -

I am currently taking a course in control theory and are assigned a
number of Matlab-based problems.  One problem discusses the use of the
'series' function, used to cascade two systems in series.  When I call
this function in Octave, I get a warning that the function is obsolete,
and to use 'sysmult' instead.  I am sure that 'sysmult' is a fine
function, but if the goal with Octave is Matlab compatibility (I've been
told more than once that it is), why create a similar function with a
different name?  Why not improve the existing series function and keep
the name?
