Notes about the pdeplot, pdesurf and pdemesh Octave functions:
3
These functions are Free Software reimplementations of the corresponding
4
functions in Matlab's PDE Toolbox.
6
They require the external program "ivview" included in the open source
7
Open Inventor distribution which can be obtained from
9
http://oss.sgi.com/projects/inventor/.
11
Open Inventor also exists in the package system of some Linux
12
distributions, such as Debian (the package inventor-clients).
14
They have been verified to work in Octave 2.1.50.

Bugs and comments on features:
23
The functions use the "popen2" call in Octave to communicate with
24
"ivview", and this does not always work correctly, "ivview" can
25
sometimes hang. This is presumably an Octave bug.

The pdeplot function is a far from complete reimplementation of the
