💖 TESTING/LIN/schkaa.F 💖

okay bestie, we're cracking open TESTING/LIN/schkaa.F from the LAPACK manual (that's LAPACK, section 3 — you already knew that tho 👑). buckle up, this one's the main character of the real-LAPACK test suite.

✨ SYNOPSIS ✨

Functions/Subroutines

  • program schkaa
    • SCHKAA

🎀 Function/Subroutine Documentation 🎀

program schkaa

SCHKAA

Purpose:

SCHKAA is literally THE main test program for the REAL LAPACK linear equation routines. no cap, it's the whole vibe. 💅

the program must be driven by a short data file. here's the tea on how that file works:

  • the first 15 records (not counting the first comment line, okurrr) 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

and if you want an annotated example of a data file?? you can get one by deleting the first 3 characters from these following 40 lines 🫶

and now the iconic parameters themselves — every single one, no skipping 🔥

  • NMAX — INTEGER. the maximum allowable value for M and N. it's giving "upper limit, don't test it" 💀
  • 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
