TESTING/LIN/cchktp.f(3)

💖 NAME 💖

TESTING/LIN/cchktp.f — bestie, this is the manual page for TESTING/LIN/cchktp.f, aka the LAPACK tester routine cchktp doing its thing in the TESTING/LIN corner. 🎀

✨ SYNOPSIS ✨

🧚 Functions/Subroutines

       subroutine cchktp (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax,
           ap, ainvp, b, x, xact, work, rwork, nout)
           CCHKTP

🌸 Function/Subroutine Documentation 🌸

   subroutine cchktp (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, real
       thresh, logical tsterr, integer nmax, complex, dimension( * ) ap,
       complex, dimension( * ) ainvp, complex, dimension( * ) b, complex,
       dimension( * ) x, complex, dimension( * ) xact, complex, dimension( * )
       work, real, dimension( * ) rwork, integer nout)
       CCHKTP

🦋 Purpose

Okay so the whole vibe is: CCHKTP tests CTPTRI, -TRS, -RFS, and -CON, and CLATPS. That’s the purpose, periodt. ✨

💅 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are 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 column 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.
• NMAX — NMAX is INTEGER. The leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL.
• AP — AP is COMPLEX array, dimension (NMAX*(NMAX+1)/2).
• AINVP — AINVP is COMPLEX array, dimension (NMAX*(NMAX+1)/2).
• B — B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX 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.
