💖 TESTING/LIN/zchkhp.f 💖

okay bestie, this is the zchkhp page from the Library Functions Manual, and it's lowkey all about testing the ZHPTRF, -TRI, -TRS, -RFS, and -CON routines. no cap, let's get into it. ✨

    dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
    precision thresh, logical tsterr, integer nmax, complex*16, dimension( *

    ZCHKHP

🔥 Purpose 🔥

ZCHKHP tests ZHPTRF, -TRI, -TRS, -RFS, and -CON. periodt. 💜

🌈 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 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.
• 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+1)/2).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• 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(2,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NSMAX).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
