openmc.legendre_from_expcoef

openmc.legendre_from_expcoef(coef, domain=(-1, 1))[source]

Return a Legendre series object based on expansion coefficients.

Given a list of coefficients from FET tally and a array of down, return the numpy Legendre object.

Parameters:

coef (Iterable of float) – A list of coefficients of each term in Legendre polynomials
domain ((2,) List of float) – Domain of the Legendre polynomial

Returns:

A numpy Legendre series class

Return type:

numpy.polynomial.Legendre
