eigenvalue_spectral

spheroidal.spectral.eigenvalue_spectral(s, ell, m, g, num_terms=None, n_max=100)

Computes the spin-weighted spheroidal eigenvalue with spin-weight s, degree l, order m, and spheroidicity g

Parameters:

• s (int or half-integer float) – spin weight

• ell (int or half-integer float) – degree

• m (int or half-integer float) – order

• g (complex) – spheroidicity

• num_terms (int) – number of terms in the spherical expansion, automatic by default

• n_max (int) – maximum number of terms in the spherical expansion, defaults to 100

Returns:

spin-weighted spheroidal eigenvalue \({}_{s}\lambda_{lm}\)

Return type:

double
