Function
NumCosmoMathSpectralgegenbauer_alpha1_eval
Declaration [src]
gdouble
ncm_spectral_gegenbauer_alpha1_eval (
GArray* c,
gdouble t
)
Description [src]
Evaluates a Gegenbauer $C^{(1)}_n$ expansion at t using a stable recurrence
(with $C^{(1)}_n = U_n$). The variable t should be in the interval [-1, 1]. To
evaluate at a point x in [a, b], use ncm_spectral_gegenbauer_alpha1_eval_x() or
first convert x to t using ncm_spectral_x_to_t().
