🦋 Function/Subroutine Documentation 🦋

subroutine SCHKSY

subroutine SCHKSY (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
    nns, integer, dimension( * ) nsval, real thresh, logical tsterr, integer
    nmax, real, dimension( * ) a, real, dimension( * ) afac, real,
    dimension( * ) ainv, real, dimension( * ) b, real, dimension( * ) x,

    SCHKSY

🎀 Purpose 🎀

Okay so, literally, SCHKSY tests SSYTRF, -TRI2, -TRS, -TRS2, -RFS, and -CON. That's the whole purpose, periodt. No cap.

🌸 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 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 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 maximum value permitted for N, used in dimensioning the work arrays.
• A — A is REAL array, dimension (NMAX*NMAX).
• AFAC — AFAC is REAL array, dimension (NMAX*NMAX).
• AINV — AINV is REAL array, dimension (NMAX*NMAX).
• 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)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
