DCHKQRTP(3)

DCHKQRTP(3) 💖

okay bestie, this one is from the Library Functions Manual, and it’s all about DCHKQRTP(3) — yes, the Fortran test routine, not a new perfume. 🎀

🌸 NAME 🌸

The NAME section is literally this path, no cap:

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

🦋 SYNOPSIS 🦋

Functions/Subroutines

subroutine DCHKQRTP (thresh, tsterr, nm, mval, nn, nval, nnb, nbval,
    nout)
    DCHKQRTP

💅 Function/Subroutine Documentation 💅

Here’s the full signature, bestie — typed exactly like the source:

subroutine DCHKQRTP (double precision thresh, logical tsterr, integer nm,
    integer, dimension( * ) mval, integer nn, integer, dimension( * ) nval,
    integer nnb, integer, dimension( * ) nbval, integer nout)
    DCHKQRTP

🎀 Purpose 🎀

The source purpose block says this, verbatim:

!>
!> DCHKQRTP tests DTPQRT and DTPMQRT.
!>

So yeah: DCHKQRTP tests DTPQRT and DTPMQRT. That’s the whole vibe. ✨

🍓 Parameters 🍓

• THRESH — THRESH is DOUBLE PRECISION. It’s the threshold value for the test ratios. A result gets included in the output file if RESULT >= THRESH. Want every test ratio printed? Set THRESH = 0. periodt 💅
• TSTERR — TSTERR is LOGICAL. It’s a flag that indicates whether error exits are to be tested.
• NM — NM is INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix column dimension N.
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• NOUT — NOUT is INTEGER. The unit number for output.
