Hi Ben, could you send me an associated test patch? Also, calling your class array might not be a good idea, as you also imported numarray.array as array.
best, Thomas

Funny you mention that Frank,
I'm currently hacking away at a py/numarray external storing control points for a Gem object.
All is great until I try and make multiple instances of the py object, things get funny. All of a sudden some methods are no longer accepted: I get an "unhandled" message, while others work fine.
Anyhow for the python hackers out there here is my current code:
(obviously some things are inefficient but I'd like to get it to work before I worry about elegance! Why might this not work when I create a second instance?)
import pyext import sys from numarray import *
class array(pyext._class):
# number of inlets and outlets _inlets=1 _outlets=1
# Vars width = 0 height = 0 points = array()
print "curve3d scripts init"

Thanks all.

I guess the iem matrix objects count from 1 because matlab/octave also counts from 1 :)
Well, there's always numarray. ;)
