Fwd: operator concept in Octave?

[Jordi Gutierrez Hermoso]

Siegfried has asked me to forward to the Octave mailing lists his
thoughts about operator overloading in Octave, apparently the only
obstacle for being able to contribute to Octave useful M**TLAB code of
his. His code can be found in his homepage listed below.

Plese do so! The INTLAB code is on my homepage

Believe me, there are numerous applications and packages using
Matlab's operator concept. Handling is, as always, extremely simple.
