Hi, Marcus.

Saving graphs in *.fig must also be supported...It is possible to use
save, and saveas for saving figures?  Does save and/or saveas calls
hgsave as well?

Or this Figure create *.mat files and a set of commands to recreate the
figure?


Oplot supports VRML now, but this is very different from Figure format
used by M*lab.

What you need first, is an option in the visualisation application that
says:
Example:  "Generate m-code to recreate figure", which create mat-files
and so forth...

To do this without any problems, octplot and oplot must be redesigned I
guess. They need to use an embedded octave to be able to send commands
back to Octave.

Octave-GUI made by Sebastien are actually using the embedded octave
feature.

John/Paul:
Is it possible to send command to an active octave instance from an
external application?
How can this be done?
