contour.m by Shai Ayal

[Henry F. Mollet]

I'm trying to use Shai's contour.m (see attached 3 files). I've recompiled
contourl.cc to get the oct file to be on the save side and then tried
contour (x,y,z):
error: can't perform indexing operations for <unknown type> type. When I
changed to the directory with the Octave contour.m it worked but this does
not use an oct file.

What am I doing incorrectly?  It worked for Shai in March 2005 in GNU
Octave, version 2.1.57 (i686-pc-linux-gnu).
