🌸 NAME 🌸

This is the TESTING/LI...a_2stage.f(3) page from the Library Functions Manual, bestie, and the file in question is TESTING/LIN/zchksy_aa_2stage.f. It’s giving β€œLAPACK test routine main character energy” ✨


✨ SYNOPSIS ✨

           thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork,
           nout)

🫢 Purpose

ZCHKSY_AA_2STAGE tests ZSYTRF_AA_2STAGE, -TRS_AA_2STAGE. That’s the whole mood πŸ’– no cap.

πŸŽ€ Parameters

  • DOTYPE β€” DOTYPE is LOGICAL array, dimension (NTYPES). These are the matrix types 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. So it’s literally a little β€œdo I run this type?” yes/no list 🫢
  • NN β€” NN is INTEGER. The number of values of N contained in the vector NVAL.
  • NVAL β€” NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N.
  • NNB β€” NNB is INTEGER. The number of values of NB contained in the vector NBVAL.
  • NBVAL β€” NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
  • NNS β€” NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
  • NSVAL β€” NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
  • THRESH β€” THRESH is DOUBLE PRECISION. 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. So if you want maximum tea, set it to zero πŸ‘€
  • TSTERR β€” TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
  • NMAX β€” NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
  • A β€” A is COMPLEX*16 array, dimension (NMAX*NMAX).
  • AFAC β€” AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
  • AINV β€” AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
  • B β€” B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
  • X β€” X is COMPLEX*16 array, dimension (NMAX*NSMAX).
  • XACT β€” XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
  • WORK β€” WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
  • RWORK β€” RWORK is COMPLEX*16 array, dimension (max(NMAX,2*NSMAX)).
  • IWORK β€” IWORK is INTEGER array, dimension (2*NMAX).
  • NOUT β€” NOUT is INTEGER. The unit number for output.

Mwah πŸ’‹ cute little sign-off: this page is sourced from LAPACK Version 3.12.0 and its footer page name is TESTING/LI...a_2stage.f(3). There’s no date in the footer, bestie, so I’m not inventing one 🫢✨
