💖 lis_vector_nrm2 — Lis Library Functions 💖

okay so bestie, welcome to the lis_vector_nrm2(3f) page, aka the one where we find out how long a vector is. not in a "how many numbers" way, in a "how big is this thing in space" way. it's giving math but make it cute. ✨

🌸 NAME 🌸

lis_vector_nrm2 — calculate the 2-norm of the vector

like. the vibe is literally right there in the name. nrm2. norm. two. iykyk. 🎀

✨ SYNOPSIS ✨

subroutine lis_vector_nrm2(LIS_VECTOR x, LIS_REAL *value, LIS_INTEGER
ierr);

three things go in, one of them is an error code because it's Fortran and that's just how we live. 💅

🦋 DESCRIPTION 🦋

Calculate the 2-norm of vector x.

that's it. that's the whole thing. the 2-norm is the length-y, magnitude-y number for your vector, and this subroutine hands it to you. no cap, it's a one-job icon and it does the job. 👑

🍓 INPUT 🍓

• x — The vector. yes girl, the actual vector, the one you want measured. bring it. 🫶

💜 OUTPUT 💜

• value — The 2-norm of the vector. this is where the answer lands. catch it. 🎀

🌈 SEE ALSO 🌈

• lis(3) — the whole Lis library, the mothership, the main character. go say hi. 💖

and that's the page, bestie!! 💅✨ this one came from the Lis Library Functions manual, filed under lis_vector_nrm2(3f), and it was dated 10 Oct 2016. mwah. go measure something. 🦋🌸💖
