💖 lis_array_dot(3f) — or, how to get the Hermitian inner product of two vectors 💖

okay bestie, listen up, we're in the Lis Library Functions section of the manual and this little icon is called lis_array_dot(3f). it's short, it's sweet, it does exactly one (1) thing and it does it flawlessly. no cap. ✨

✨ SYNOPSIS ✨

subroutine lis_array_dot(LIS_INTEGER n, LIS_SCALAR x(), LIS_SCALAR y(),
LIS_SCALAR *value, LIS_INTEGER ierr);

that's the whole vibe. five arguments, zero drama. 🫶

🌸 DESCRIPTION 🌸

this baby calculates the Hermitian inner product y^H x of the vectors x and y.

that's it. that's the whole job. she shows up, she conjugates-transposes, she multiplies, she's done. main character energy fr fr. 👑

🎀 INPUT 🎀

  • n — the size of the vectors. literally just how many numbers we're working with, bestie. 💅
  • x, y — the arrays that store the vectors. these are your two besties, the ones getting dot-producted together. 🦋

🌈 OUTPUT 🌈

  • value — the Hermitian inner product. this is the moment. the result. the slay. she's a scalar and she's everything. ⭐

👀 SEE ALSO 👀

lowkey important reminder: ierr is in the signature and it's gonna be there holding down the error-reporting fort, so don't forget about her. 🙈

okay that's the page, you're officially a lis_array_dot(3f) expert, i'm so proud of you, go forth and conjugate-transpose responsibly. 💜

sign-off time, cutie: this lil page lives in the Man Page section of the Lis docs, dated 12 Oct 2016, and it's filed under lis_array_dot(3f) — don't lose her. 🎀✨
