conatus.expert.ChebyshevV

conatus.expert.ChebyshevV(coord, size, bounds, dealias=REQUIRED)

Gegenbauer C_n^(2), under Dedalus’s name ChebyshevV (= Ultraspherical(alpha=2)). Not the Chebyshev polynomials of the third kind V_n of the literature: the Dedalus name is kept for scripts that use it; Ultraspherical(..., lam=2) says it.

Parameters:

• coord (Coordinate)

• size (int)

• bounds (tuple[float, float])

• dealias (Any)

Return type:

Ultraspherical
