how to use 'convolve/filter' package?

Hello there,

My name is Nao Suzuki and I'm a postdoc at Berkeley Lab.

I've been using numarray about a year, and I found it
very useful and I appreciate your excellent work!

Today, I've been trying to take the advantage of filter
packages but none of them work so far.  Here is the
attempt to reproduce what's shown in the manual.

>>> from numarray import *
>>> a=[0,0,0,1,0,0,0]
>>> correlate1d(a, [1, 1, 1])
Traceback (most recent call last):
    File "<stdin>", line 1, in ?
NameError: name 'correlate1d' is not defined

Could someone tell me what I'm missing?  Do I need to include
something special?  Please let me know if you can give me some
hints.  I'm stuck here for long time now.

Thank you very much!
