POLY(3pm)

💖 NAME 💖

PDL::GSLSF::POLY — it's the PDL interface to GSL Special Functions, bestie. That's the whole vibe. 🎀

---

✨ DESCRIPTION ✨

Okay so real talk: this is an interface to the Special Function package chillin' inside the GNU Scientific Library. That's it, that's the job. 💅

NOTE: lowkey this should actually be PDL::POLY for consistency, but bestie, nobody wants to get into edits changing the directory structure right now, okay?? Not the moment. 🙈 These fixes should allow things to build, and honestly that's the win. ✨

🌸 FUNCTIONS 🌸

🦋 gsl_poly_eval

Signature, bestie, exactly as it is:

Signature: (double x(); double c(m); double [o]y())

And what it's giving mathematically is this iconic polynomial situation:

c[0] + c[1] x + c[2] x^2 + ... + c[m-1] x^(m-1)

gsl_poly_eval does not process bad values, no cap. 🚫 It will set the bad-value flag on all output ndarrays if the flag is set for any of the input ndarrays. That's just how it moves. 💀
