shamrock.external.coala.utils_polynomials.legendre_coeffs(kpol)

Returns a matrix (kpol+1,kpol+1) containing on each line the coefficients for each Legendre polynomial, from degree 0 to kpol inclusive. On each line coefficients are ordered from low to high orders.

Parameters

kpolscalar, type -> float

degree of polynomials for approximation

Returns

mat_coeffs_leg2D array (dmin = (kpol+1,kpol+1)), type -> float

array containing the coefficients for Legendre polynomials up to degree kpol
