DDRVPP(3)

🎀 ddrvpp.f — Library Functions Manual 🎀

Okay bestie, welcome to the ddrvpp.f page from the Library Functions Manual. This is the LAPACK page that tests the driver routines DPPSV and -SVX, and the page identifier is /home/abui...IN/ddrvpp.f(3). It’s giving “I run the tests so the solvers can shine.” ✨

🌟 Purpose 🌟

DDRVPP tests the driver routines DPPSV and -SVX. Periodt. 💅

🎀 Parameters 🎀

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are 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.
• 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+1)/2).
• AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• ASAV — ASAV is DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• 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 (NMAX).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS)).
• 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.

Cute sign-off: this page is LAPACK Version 3.12.0, page id /home/abui...IN/ddrvpp.f(3) — the footer doesn’t show a date, so no date to spill. Bye bestie, go test those driver routines! 💖✨🎀
