You are trying to call one octave function from another
octave function.  To do this, you have to marshall the
arguments and return values through an octave_value_list

I would refer you to the page I put up on the octave wiki
at gnufans.net/octave.pl, but it isn't responding.  We
need to move it to a more reliable machine.  Anyone
got something available which they don't mind having
a small wiki on?  Preferably one that can pretend it
is wiki.octave.org.  Can we do this on source forge?

Search the octave mailing list at http://www.octave.org
for an example.

The alternative approach used in a number of  files
in octave/src/DLD_FUNCTIONS is to define an
internal function f, and two DLD_FUNCTIONS
funkprojekt_oct and f which call the internal f and
compile them into the same oct-file.  To access f from
octave, you need to symlink f.oct to funkproject_oct.oct,
or vice versa depending on what you call the oct-file.

I would put this info in the wiki, too, if it were up.
