I am trying to calculate the 720th Legendre polynomial with scipy:
>>>from scipy.special import legendre
>>>print(legendre(720))
it prints the powers correctly but returns NAN for the coefficients how can I fix this?
It's probably a float
overflow error . If you use the monic
keyword of the legendre
function you get non- nan
coefficients:
>>> from scipy.special import legendre
>>> print(legendre(720, monic=True))
720 sounds like a high number, maybe it's more stable to use the eval_legendre
function.
