Hi,
On my box,
from scipy.special import *
import scipy.special._cephes as cephes
cephes.pbdv(1,0)
returns
(0.0, 1.0)
As a result, assert_equal(cephes.pbdv(1,0),(0.0,0.0)) from
"/usr/lib/python2.5/site-packages/scipy/special/tests/test_basic.py",line
357 fails.
First can someone reproduce this bug?
I'm using ubuntu intrepid 64bits.
Second, if my understanding of pbdv is supposed to do, (0.0, 1.0) is the
correct answer.
