🎀 Purpose 🎀

DDRVGE tests the driver routines DGESV, -SVX, and -SVXX.

Honey, heads up: this file is used only when the XBLAS are available, otherwise ddrvge.f defines this subroutine. 🫶

🌸 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.
• 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).
• ASAV — ASAV is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• BSAV — BSAV is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• X — X is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• S — S is DOUBLE PRECISION array, dimension (2*NMAX).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (2*NRHS+NMAX).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
