[Eeglablist] Associated Legendre polynomial

[Birju Patel]

Hi,

I've noticed that the implementation of the legendre polynomials in the
dipole fitting plugin includes the (-1)^m phase factor in the definition of
the associated legendre polynomial of order m (the 3-shell model uses order
m=1).  However, most of the references sited in the literature of the
3-shell model point back to old (1930 - 1950) physics texts, where the
associated legendre polynomial is defined without the (-1)^m factor.

Does anyone know if the 3-shell model equations change with these two
slightly different definitions of the Legendre polynomial?

Thank you,
Birju Patel
