💅 DCHKSY_ROOK(3)

okay so welcome to the Library Functions Manual, bestie — this is the page for TESTING/LIN/dchksy_rook.f. she’s the test routine for the _ROOK family listed below, and she did not come to play. ✨

       DCHKSY_ROOK

🎯 Purpose

DCHKSY_ROOK tests DSYTRF_ROOK, -TRI_ROOK, -TRS_ROOK, and -CON_ROOK. 🫶

🌸 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. 🎀
• 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 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 DOUBLE PRECISION array, dimension (NMAX*NMAX). 🌈
• AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX). ⭐
• AINV — AINV is DOUBLE PRECISION array, dimension (NMAX*NMAX). 💀
• B — B is DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. 🙈
• X — X is DOUBLE PRECISION array, dimension (NMAX*NSMAX). 🍓
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX). 🧚
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)). 💜
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)). 🌸
• IWORK — IWORK is INTEGER array, dimension (2*NMAX). 🦋
• NOUT — NOUT is INTEGER. The unit number for output. 🎀
