ALAERH(3)

✨ ALAERH(3) ✨

Okay bestie, you're reading ALAERH(3) from the Library Functions Manual — it's giving very specific LAPACK error-handler main character energy, and honestly? Iconic. 🫶

💖 NAME 💖

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/alaerh.f

🦋 SYNOPSIS 🦋

This page is filed under Functions/Subroutines:

subroutine ALAERH (path, subnam, info, infoe, opts, m, n, kl, ku, n5,
    imat, nfail, nerrs, nout)
    ALAERH

🌸 Function/Subroutine Documentation 🌸

Here's the full signature, exactly as it appears, no cap:

subroutine ALAERH (character*3 path, character*( * ) subnam, integer info,
    integer infoe, character*( * ) opts, integer m, integer n, integer kl,
    integer ku, integer n5, integer imat, integer nfail, integer nerrs,
    integer nout)
    ALAERH

✨ Purpose ✨

ALAERH is an error handler for the LAPACK routines. It prints the header if this is the first error message, and it prints the error code and form of recovery, if any. The character evaluations in this routine may make it slow, but it should not be called once the LAPACK routines are fully debugged.

Lowkey: this is the “something went wrong” girlie of the LAPACK test suite, and she has receipts. 💅

🎀 Parameters 🎀

• PATH — is CHARACTER*3; the LAPACK path name of subroutine SUBNAM.
• SUBNAM — is CHARACTER*(*); the name of the subroutine that returned an error code.
• INFO — is INTEGER; the error code returned from routine SUBNAM.
• INFOE — is INTEGER; the expected error code from routine SUBNAM, if SUBNAM were error-free. If INFOE = 0, an error message is printed, but if INFOE.NE.0, we assume only the return code INFO is wrong.
• OPTS — is CHARACTER*(*); the character options to the subroutine SUBNAM, concatenated into a single character string. For example, UPLO = 'U', TRANS = 'T', and DIAG = 'N' for a triangular routine would be specified as OPTS = 'UTN'.
• M — is INTEGER; the matrix row dimension.
• N — is INTEGER; the matrix column dimension. Accessed only if PATH = xGE or xGB.
• KL — is INTEGER; the number of sub-diagonals of the matrix. Accessed only if PATH = xGB, xPB, or xTB. Also used for NRHS for PATH = xLS.
• KU — is INTEGER; the number of super-diagonals of the matrix. Accessed only if PATH = xGB.
• N5 — is INTEGER; a fifth integer parameter, may be the blocksize NB or the number of right hand sides NRHS.
• IMAT — is INTEGER; the matrix type.
• NFAIL — is INTEGER; the number of prior tests that did not pass the threshold; used to determine if the header should be printed.
• NERRS — is INTEGER; on entry, the number of errors already detected; used to determine if the header should be printed. On exit, NERRS is increased by 1.
• NOUT — is INTEGER; the unit number on which results are to be printed.
