Re: Octave/C++

[Søren Hauberg]

Hi,
I haven't looked at the code you provided a link to, but here goes...
From what I understand C++ robot interface basicly consist of a 
"robot_link" object that you have to provide each to you want the robot 
to act. I'd say the easiest thing to do is to create a new octave type 
in C++ that contains a "robot_link" and then write wrapper functions to 
the functions your students need to access.
A tutorial on how to write new types for Octave can be found at 
http://wiki.octave.org/wiki.pl?CodaTypes

Hope this helps, if not write again. Your problem should be fairly easy 
to solve, although it will require a bit of work.
