TESTING/LIN/schkpt.f(3)

🌸 NAME 🌸

TESTING/LIN/schkpt.f — okay so this is the manual page for the schkpt subroutine in LAPACK’s TESTING/LIN corner. The page title vibe is TESTING/LIN/schkpt.f(3), and the main character is schkpt, no cap. 💖

🌟 Purpose 🌟

!>
!> SCHKPT tests SPTTRF, -TRS, -RFS, and -CON
!>

So yeah — SCHKPT tests SPTTRF, -TRS, -RFS, and -CON. That’s the whole assignment, bestie. 💅

💖 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.
• 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 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 REAL array, dimension (NMAX*2).
• D — D is REAL array, dimension (NMAX*2).
• E — E is REAL array, dimension (NMAX*2).
• B — B is REAL array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is REAL array, dimension (NMAX*NSMAX).
• XACT — XACT is REAL array, dimension (NMAX*NSMAX).
• WORK — WORK is REAL array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER. The unit number for output.
