💅 TESTING/LIN/cchkpo.f — Library Functions Manual energy ✨

okay so bestie, this is the Library Functions Manual page for TESTING/LIN/cchkpo.f. It's giving testing-documentation realness, and we're keeping every single deet. 🫶

CCHKPO — that's the name, periodt. 💅

🎀 Purpose 🎀

CCHKPO tests CPOTRF, -TRI, -TRS, -RFS, and -CON. That's literally what it does. ✨

🌟 Parameters 🌟

  • DOTYPE — is a 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. No cap.
  • NN — is INTEGER. The number of values of N contained in the vector NVAL.
  • NVAL — is INTEGER array, dimension (NN). The values of the matrix dimension N.
  • NNB — is INTEGER. The number of values of NB contained in the vector NBVAL.
  • NBVAL — is INTEGER array, dimension (NNB). The values of the blocksize NB.
  • NNS — is INTEGER. The number of values of NRHS contained in the vector NSVAL.
  • NSVAL — is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
  • 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. Obsessed with that zero-threshold life.
  • TSTERR — is LOGICAL. Flag that indicates whether error exits are to be tested.
  • NMAX — is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
  • A — is COMPLEX array, dimension (NMAX*NMAX).
  • AFAC — is COMPLEX array, dimension (NMAX*NMAX).
  • AINV — is COMPLEX array, dimension (NMAX*NMAX).
  • B — is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
  • X — is COMPLEX array, dimension (NMAX*NSMAX).
  • XACT — is COMPLEX array, dimension (NMAX*NSMAX).
  • WORK — is COMPLEX array, dimension (NMAX*max(3,NSMAX)).
  • RWORK — is REAL array, dimension (NMAX+2*NSMAX).
  • NOUT — is INTEGER. The unit number for output.
