TESTING/LIN/zdrvgb.f(3) 💖✨

okay bestie, welcome to TESTING/LIN/zdrvgb.f from the Library Functions Manual — this page is iconic for ZDRVGB, and it’s literally testing the driver routines ZGBSV and -SVX 💅

🌸 Purpose 🌸

ZDRVGB tests the driver routines ZGBSV and -SVX. 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 column dimension N. ✨
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. 🦋
• 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. 👑
• A — A is COMPLEX*16 array, dimension (LA). 🌈
• LA — LA is INTEGER. The length of the array A. LA >= (2*NMAX-1)*NMAX where NMAX is the largest entry in NVAL. 💜
• AFB — AFB is COMPLEX*16 array, dimension (LAFB). 🍓
• LAFB — LAFB is INTEGER. The length of the array AFB. LAFB >= (3*NMAX-2)*NMAX where NMAX is the largest entry in NVAL. 🌟
• ASAV — ASAV is COMPLEX*16 array, dimension (LA). 🎀
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS). 💖
• BSAV — BSAV is COMPLEX*16 array, dimension (NMAX*NRHS). ✨
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS). 🦋
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS). 🔥
• S — S is DOUBLE PRECISION array, dimension (2*NMAX). 👑
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NRHS,NMAX)). 🌈
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS). 💜
• IWORK — IWORK is INTEGER array, dimension (NMAX). 🍓
• NOUT — NOUT is INTEGER. The unit number for output. 🌟
