[SciPy-user] Way to get values which are the same on two arrays

[José Luis Gómez Dans]

Hi,
	I seem to remember a Numerical function that could produce the list of 
values (or array positions) which are common to two arrays. In other 
words:
a1=[1,2,3,9,10]
a2=[1,4,9,10]
	result is [1,9,10].

	Browsing through the Numerical docs doesn't refresh my memory, so any 
kind souls?

	many thanks,
José
