One mroe question from me today :)

I have some trouble running polyfit with matplotlib-0.52
Can you please help me finding out what I do wrong=20
I give a list of x values and y values as well as the degree of the desired=
 polynome. But all I get is the following error

>>> x=3D[1,2,3]
>>> y=3D[1,2,1]
>>> polyfit(x,y,3)
Traceback (most recent call last):
  File "<<console>>", line 1, in ?
  File "/usr/lib/python2.2/site-packages/matplotlib/mlab.py", line 341, in =
polyfit
    X =3D Matrix(vander(x, N+1))
  File "/usr/lib/python2.2/site-packages/matplotlib/mlab.py", line 383, in =
vander
    X =3D ones( (len(x),N), x.typecode())
AttributeError: 'list' object has no attribute 'typecode'


Any idea ?

Thanks

Jean-Baptiste
