GEGENBAUER(3pm)

💖 GEGENBAUER 💖

okay bestie, sit down, hydrate, and let me tell you about GEGENBAUER — it's a 3pm page, which means it's user-contributed Perl documentation, and it's literally the whole vibe. no cap. 🎀

---

✨ NAME ✨

PDL::GSLSF::GEGENBAUER — it's the PDL interface to GSL Special Functions. that's it, that's the name. short, sweet, iconic. 💅

---

🌸 DESCRIPTION 🌸

So basically: this is an interface to the Special Function package that lives inside the GNU Scientific Library. it's giving "PDL said lemme hold your hand while you call GSL". 🦋

---

🔥 FUNCTIONS 🔥

⭐ gsl_sf_gegenpoly_n

the signature, verbatim, don't come for me:

Signature: (double x(); double [o]y(); double [o]e(); int n; double lambda)

Evaluate Gegenbauer polynomials. slay. ✨

lowkey important: gsl_sf_gegenpoly_n does not process bad values. it will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays. so like, mind the flags bestie. 😭

---

🦋 gsl_sf_gegenpoly_array

signature time:

Signature: (double x(); double [o]y(num); int n=>num; double lambda)

Calculate an array of Gegenbauer polynomials from 0 to n-1. it's giving range energy. periodt. 👑

same warning, same drama: gsl_sf_gegenpoly_array does not process bad values, and it will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.
