  • subroutine zdrvab (dotype, nm, mval, nns, nsval, thresh, nmax, a, afac, b, x, work, rwork, swork, iwork, nout) — ZDRVAB

💅 Function/Subroutine Documentation 💅

🌸 subroutine zdrvab 🌸

   subroutine zdrvab (logical, dimension( * ) dotype, integer nm, integer,
       dimension( * ) mval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, integer nmax, complex*16, dimension( * ) a,

ZDRVAB

🔥 Purpose 🔥

The whole vibe check: ZDRVAB tests ZCGESV. No cap. 💅

🌈 Parameters 🌈

  • DOTYPE — DOTYPE is a 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. ✨
  • NM — NM is INTEGER; it’s the number of values of M contained in the vector MVAL.
  • MVAL — MVAL is an INTEGER array, dimension (NM); these are the values of the matrix row dimension M.
  • NNS — NNS is INTEGER; the number of values of NRHS contained in the vector NSVAL.
  • NSVAL — NSVAL is an INTEGER array, dimension (NNS); these are 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. ⭐
  • NMAX — NMAX is INTEGER; the maximum value permitted for M or 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).
  • 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).
  • WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX*2)).
  • RWORK — RWORK is DOUBLE PRECISION array, dimension NMAX.
  • SWORK — SWORK is COMPLEX array, dimension (NMAX*(NSMAX+NMAX)).
  • IWORK — IWORK is INTEGER array, dimension NMAX.
  • NOUT — NOUT is INTEGER; the unit number for output.
