spectral_matrix_bands

spheroidal.spherical.spectral_matrix_bands(s, m, g, num_terms)

Returns the diagonal bands of the matrix used to compute the spherical-spheroidal mixing coefficients.

Parameters:

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

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

• g (complex) – spheroidicity

• num_terms (int) – dimension of matrix

• offset (int) – index along the main diagonal at which to start computing terms

Returns:

array of shape (3,num_terms) containing the main diagonal of the matrix followed by the two diagonals below it

Return type:
