DDRVAC(3)

💖 ddrvac.f(3) — Library Functions Manual 💖

okay bestie, welcome to the whole manual page for /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/ddrvac.f in the Library Functions Manual. It's giving niche LAPACK testing energy, and honestly we're obsessed. 🫶

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/ddrvac.f

That's the name, bestie — yes, the entire path. No cap. 💅

✨ SYNOPSIS ✨

Functions/Subroutines

       subroutine DDRVAC (dotype, nm, mval, nns, nsval, thresh, nmax, a, afac,
           b, x, work, rwork, swork, nout)
           DDRVAC

💅 Function/Subroutine Documentation 💅

DDRVAC

   subroutine DDRVAC (logical, dimension( * ) dotype, integer nm, integer,
       dimension( * ) mval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, integer nmax, double precision, dimension( * ) a,
       double precision, dimension( * ) afac, double precision, dimension( * )
       b, double precision, dimension( * ) x, double precision, dimension( * )
       work, double precision, dimension( * ) rwork, real, dimension(*) swork,
       integer nout)

🎯 Purpose: 🎯

Purpose unlocked: DDRVAC tests DSPOSV. That's the whole purpose, and it's iconic. 😭💖

🌈 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. 💅
• NM — NM is INTEGER. The number of values of N contained in the vector MVAL. ✨
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix dimension N. 🎀
• 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. 🔥
• 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). 🌈
• B — B is DOUBLE PRECISION array, dimension (NMAX*NSMAX). 💜
• X — X 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(2*NMAX,2*NSMAX+NWORK)). 🙈
• SWORK — SWORK is REAL array, dimension (NMAX*(NSMAX+NMAX)). 💀
• NOUT — NOUT is INTEGER. The unit number for output. 🫶

okay bestie, that's the whole page 💖✨ the footer vibe is LAPACK Version 3.12.0 and the page path /home/abui...IN/ddrvac.f(3). It was generated automatically by Doxygen for LAPACK from the source code, and it ate. Byeeeee 👑🫶
