TESTING/LIN/cdrvgt.f(3) 🦋

okay so this is the Library Functions Manual page for TESTING/LIN/cdrvgt.f, and it’s giving “I test linear algebra routines and I have receipts” energy. we’re documenting the CDRVGT subroutine, no cap. 💅

✨ NAME ✨

TESTING/LIN/cdrvgt.f

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

   subroutine cdrvgt (dotype, nn, nval, nrhs, thresh, tsterr, a, af, b, x,
       xact, work, rwork, iwork, nout)
           CDRVGT

🌸 Function/Subroutine Documentation 🌸

   subroutine cdrvgt (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, real thresh, logical tsterr, complex,
       dimension( * ) a, complex, dimension( * ) af, complex, dimension( * ) b,
       complex, dimension( * ) x, complex, dimension( * ) xact, complex,
       dimension( * ) work, real, dimension( * ) rwork, integer, dimension( * )
       iwork, integer nout)
       CDRVGT

🎀 Purpose 🎀

CDRVGT tests CGTSV and -SVX. that’s the whole purpose, and it ate. periodt. ✨

🧚 Parameters 🧚

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). The matrix types to be used for testing. Matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
• 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 dimension N.
• NRHS — NRHS is INTEGER. The number of right hand sides, NRHS >= 0.
• THRESH — THRESH is REAL. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• A — A is COMPLEX array, dimension (NMAX*4).
• AF — AF is COMPLEX array, dimension (NMAX*4).
• B — B is COMPLEX array, dimension (NMAX*NRHS).
• X — X is COMPLEX array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX array, dimension (NMAX*NRHS).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NRHS)).
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

bestie, THRESH = 0 is the “print every test ratio” mode, so the output file is gonna be chatty. 💬
