some body who can explain for me the Legndre polynomials:eek: :eek:
 
Physics news on Phys.org
What do you want to know and what do you already know about them:eek: :eek:

Surely, nobody will be willing to type the whole theory behind them so be more specific please:eek: :eek:

A set of polynomials dependent on continuous variable x and integers m (and sometimes n) which have useful orthogonality and spanning properties.

Known to have useful solutions when dealing with spherical coordinates and potentials. Want more info? There's a fantastic website I know called Google. It'll find anything for you ;)
 
Legendre Polynomials

I need some help. I fitted a 7th order legendre polynomial and got the L0 to L7 coefficients for different classes. How can I get a back transformation in order to plot each class using the estimated coefficients?
Thanks to anybody.
Roberto.
