lapacke_cgtsvx.c(3)

🎀 lapacke_cgtsvx.c 🎀

okay so bestie, welcome to the LAPACK docs — this one lives in the <pink>LAPACK</pink> manual, and it's the page for lapacke_cgtsvx.c. yeah. the file's name is literally the title. iconic behavior, no notes. 💅

---

✨ NAME ✨

lapacke_cgtsvx.c — that's it, that's the name, she said what she said 🫶

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header, and it's written with those single quotes exactly like this:

#include 'lapacke_utils.h'

💜 Functions

there's exactly one function on this page, and it's a whole main character:

lapack_int LAPACKE_cgtsvx (int matrix_layout, char fact, char trans,
    lapack_int n, lapack_int nrhs, const lapack_complex_float *dl, const
    lapack_complex_float *d, const lapack_complex_float *du,
    lapack_complex_float *dlf, lapack_complex_float *df,
    lapack_complex_float *duf, lapack_complex_float *du2, lapack_int
    *ipiv, const lapack_complex_float *b, lapack_int ldb,
    lapack_complex_float *x, lapack_int ldx, float *rcond, float *ferr,
    float *berr)

like, look at that parameter list. it's giving final boss energy. 😭 copy it exactly, don't be out here retyping it from memory, i'm begging.

🔥 Function Documentation 🔥

⭐ lapack_int LAPACKE_cgtsvx (...)

here's the full signature again, formatted all pretty, every param spelled out with the exact types and the exact const-ness, because the const situation on this one is real and you do not want to fumble it:

lapack_int LAPACKE_cgtsvx (int matrix_layout, char fact, char trans,
    lapack_int n, lapack_int nrhs, const lapack_complex_float * dl, const
    lapack_complex_float * d, const lapack_complex_float * du,
    lapack_complex_float * dlf, lapack_complex_float * df,
    lapack_complex_float * duf, lapack_complex_float * du2, lapack_int *
    ipiv, const lapack_complex_float * b, lapack_int ldb,
    lapack_complex_float * x, lapack_int ldx, float * rcond, float * ferr,
    float * berr)

quick vibe check on the parameter lineup, so you know what you're dealing with 💖:

• int matrix_layout — an int, and honestly the vibe-setter of the whole call.
• char fact — a single char. tiny but powerful.
• char trans — another char.
• lapack_int n — a lapack_int. yes bestie, lapack_int, not plain int.
• lapack_int nrhs — also a lapack_int.
• const lapack_complex_float *dl — pointer, marked const 🫶
• const lapack_complex_float *d — pointer, also const.
• const lapack_complex_float *du — pointer, const again. the trio is complete.
• lapack_complex_float *dlf — non-const pointer, so this one's writable.
• lapack_complex_float *df — non-const pointer.
• lapack_complex_float *duf — non-const pointer.
• lapack_complex_float *du2 — non-const pointer.
• lapack_int *ipiv — pointer to lapack_int.
• const lapack_complex_float *b — const pointer, plus a lapack_int ldb riding along with it.
• lapack_complex_float *x — pointer, plus its own lapack_int ldx.
• float *rcond — plain float out-pointer, not complex, don't get it twisted.
• float *ferr — float pointer.
• float *berr — float pointer.

ngl the whole thing is one giant call with a million arguments — if you have to type it out, just copy-paste it from above, don't freestyle it 💀
