🫶 Purpose

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

🎀 Parameters

• DOTYPE — 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 “do I run this type?” yes/no list 🫶
• 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.
• 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.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• THRESH — 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 👀
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is COMPLEX*16 array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

Mwah 💋 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 🫶✨
