💖 Function Documentation 💖

🌈 lapack_int LAPACKE_dgbrfs_work (...) 🌈

Deep breath, bestie, here's the full squad in order — every single one of them, not skipping a single member of the group chat:

lapack_int LAPACKE_dgbrfs_work (int matrix_layout, char trans, lapack_int n,
    lapack_int kl, lapack_int ku, lapack_int nrhs, const double * ab,
    lapack_int ldab, const double * afb, lapack_int ldafb, const lapack_int
    * ipiv, const double * b, lapack_int ldb, double * x, lapack_int ldx,
    double * ferr, double * berr, double * work, lapack_int * iwork)

The full roster, so you know exactly who's who and what type they're serving:

• int matrix_layout — an int, sitting first in line like it owns the place 💅
• char trans — a single char, tiny but important energy
• lapack_int n — a lapack_int
• lapack_int kl — also a lapack_int
• lapack_int ku — you guessed it, lapack_int
• lapack_int nrhs — lapack_int, still going
• const double * ab — pointer to const double
• lapack_int ldab — lapack_int
• const double * afb — const double *
• lapack_int ldafb — lapack_int
• const lapack_int * ipiv — pointer to const lapack_int
• const double * b — const double *
• lapack_int ldb — lapack_int
• double * x — a plain old double *
• lapack_int ldx — lapack_int
• double * ferr — double *
• double * berr — double *
• double * work — double * (earning its name fr fr)
• lapack_int * iwork — lapack_int *

the definition? it's chilling at line 36 of the file lapacke_dgbrfs_work.c. remember that, it might come up. 🫶
