✨ NAME ✨

TESTING/LIN/dchkaa.F — bestie, this is the source file, and the whole reason it exists is the program dchkaa hiding inside it. 💖

🦋 SYNOPSIS 🦋

  • program dchkaa

💅 Function/Subroutine Documentation 💅

program dchkaa

DCHKAA

Purpose:

DCHKAA is the main test program for the DOUBLE PRECISION LAPACK linear equation routines 🌈🔥

Okay so here's the tea 🫖 — this program does not just run itself. It must be driven by a short data file. The first 15 records (not counting the first comment line) specify problem dimensions and program options using list-directed input. The remaining lines specify the LAPACK test paths and the number of matrix types to use in testing. An annotated example of a data file can be obtained by deleting the first 3 characters from the following 40 lines:

And then the parameters, babes — these are the ones the routine is working with: 🎀

  • NMAX — INTEGER — the maximum allowable value for M and N. Like, the ceiling, the limit, the "don't even try it" number.
  • MAXIN — INTEGER — the number of different values that can be used for each of M, N, NRHS, NB, NX and RANK. 💫
  • MAXRHS — INTEGER — the maximum number of right hand sides.
  • MATMAX — INTEGER — the maximum number of matrix types to use for testing.
  • NIN — INTEGER — the unit number for input. 📥
  • NOUT — INTEGER — the unit number for output. 📤
