🎀 Purpose

Ok so CCHKHP tests CHPTRF, -TRI, -TRS, -RFS, and -CON. That’s the purpose, and it ate. 💅

🌸 Parameters

Every parameter, no gatekeeping:

• 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 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 COMPLEX array, dimension (NMAX*(NMAX+1)/2). 💜
• AFAC — AFAC is COMPLEX array, dimension (NMAX*(NMAX+1)/2). 🌈
• AINV — AINV 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(2,NSMAX)). 🫶
• RWORK — RWORK is REAL array, dimension (NMAX+2*NSMAX). 😭
• IWORK — IWORK is INTEGER array, dimension (NMAX). 🙈
• NOUT — NOUT is INTEGER. The unit number for output. 👑

Okurrr, footer tea 🫶: this is LAPACK, Version 3.12.0, page TESTING/LIN/cchkhp.f(3). The original footer has no date printed, so I’m not inventing one — periodt. 💅✨
