scipy.special.ellip_normal(h2, k2, n, p)[source]

Ellipsoidal harmonic normalization constants gamma^p_n

The normalization constant is defined as

\[\gamma^p_n=8\int_{0}^{h}dx\int_{h}^{k}dy\frac{(y^2-x^2)(E^p_n(y)E^p_n(x))^2}{\sqrt((k^2-y^2)(y^2-h^2)(h^2-x^2)(k^2-x^2)}\]
Parameters:

h2 : float

h**2

k2 : float

k**2; should be larger than h**2

n: int

Degree.

p: int

Order, can range between [1,2n+1].

Returns:

gamma : float

The normalization constant \(\gamma^p_n\)
