Function
NumCosmoMathSpectralgegenbauer_alpha2_eval
Declaration [src]
gdouble
ncm_spectral_gegenbauer_alpha2_eval (
GArray* c,
gdouble t
)
Description [src]
Evaluates a Gegenbauer $C^{(2)}_n$ expansion at t using a stable recurrence.
The variable t should be in the interval [-1, 1]. To evaluate at a point x in
[a, b], use ncm_spectral_gegenbauer_alpha2_eval_x() or first convert x to t
using ncm_spectral_x_to_t(). See the
Spectral Methods page for the
$C^{(2)}_n$ recurrence.
