But why the compatibility function is used? Not the new one from numpy? I=20
didn't ask for a Numeric compatibility?
I don't understand the need to have the Numeric function when I'm using num=
py.
I think this is a bad "feature" perhaps not a bug but not the thing that th=
e=20
majority of people would like. In my opinion, if numerix is define to be=20
numpy, all the function from numpy must be the default ones. In other hand=
=20
that will confuse plenty of people.=20
Now I understand that I have to avoid all numerix function. The problem is=
=20
that I love to use ipython pylab and so I have to be more careful when I'm=
=20
doing fast plot...
