TESTING/LIN/ddrvpp.f(3)

💖 NAME 💖

TESTING/LIN/ddrvpp.f — okay bestie, this is the manual page for that file, living in the Library Functions Manual. It’s giving LAPACK test-driver energy, and we’re gonna read it together. 🫶

🎀 Purpose 🎀

DDRVPP tests the driver routines DPPSV and -SVX. That’s the whole assignment, bestie. ✨

🌸 Parameters 🌸

• DOTYPE — 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 — INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). The values of the matrix dimension N.
• NRHS — INTEGER. The number of right hand side vectors to be generated for each linear system.
• THRESH — 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 — LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• AFAC — DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• ASAV — DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• B — DOUBLE PRECISION array, dimension (NMAX*NRHS).
• BSAV — DOUBLE PRECISION array, dimension (NMAX*NRHS).
• X — DOUBLE PRECISION array, dimension (NMAX*NRHS).
• XACT — DOUBLE PRECISION array, dimension (NMAX*NRHS).
• S — DOUBLE PRECISION array, dimension (NMAX).
• WORK — DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS)).
• RWORK — DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.

Okay that’s the whole vibe check, bestie 💅. This page is carrying LAPACK Version 3.12.0 and the page tag TESTING/LIN/ddrvpp.f(3), so that’s the source/version energy at the very end. Bye bestie, slay your tests! 🎀✨
