Nobody has any suggestion ?
:-(
PS :
In [3]: from scipy.special import *
In [4]: help(lpmn)
Help on function lpmn in module scipy.special.basic:
lpmn(m, n, z)
Associated Legendre functions of the second kind, Pmn(z) and its
derivative, Pmn'(z) of order m and degree n. Returns two
arrays of size (m+1,n+1) containing Pmn(z) and Pmn'(z) for
all orders from 0..m and degrees from 0..n.
z can be complex.
In [5]: help(lqmn)
Help on function lqmn in module scipy.special.basic:
lqmn(m, n, z)
Associated Legendre functions of the second kind, Qmn(z) and its
derivative, Qmn'(z) of order m and degree n. Returns two
arrays of size (m+1,n+1) containing Qmn(z) and Qmn'(z) for
all orders from 0..m and degrees from 0..n.
z can be complex.
lpmn should be associated Legendre functions of the first kind, no ?
Cheers,
