okay bestie, welcome to the TESTING/LIN/dchkab.f(3) page from the Library Functions Manual 💖✨

💖 NAME 💖

TESTING/LIN/dchkab.f — the file that gives us the dchkab test program, no cap.

✨ SYNOPSIS ✨

Functions/Subroutines:

  • program dchkab — DCHKAB

🌟 Function/Subroutine Documentation 🌟

🎀 program dchkab 🎀

DCHKAB

🎯 Purpose 🎯

okay so DCHKAB is the test program for the DOUBLE PRECISION LAPACK DSGESV/DSPOSV routine. iconic behavior honestly 💅

The program must be driven by a short data file. The first 5 records 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 10 lines:

!> Data file for testing DOUBLE PRECISION LAPACK DSGESV
!> 7                      Number of values of M
!> 0 1 2 3 5 10 16        Values of M (row dimension)
!> 1                      Number of values of NRHS
!> 2                      Values of NRHS (number of right hand sides)
!> 20.0                   Threshold value of test ratio
!> T                      Put T to test the LAPACK routines
!> T                      Put T to test the error exits
!> DGE    11              List types on next line if 0 < NTYPES < 11
!> DPO    9               List types on next line if 0 < NTYPES <  9
  • NMAX — INTEGER; the maximum allowable value for N 🦋
  • MAXIN — INTEGER; the number of different values that can be used for each of M, N, NRHS, NB, and NX ✨
  • MAXRHS — INTEGER; the maximum number of right hand sides 💖
  • NIN — INTEGER; the unit number for input 🎀
  • NOUT — INTEGER; the unit number for output 🌸

byeee bestie, the footer gave me LAPACK, Version 3.12.0 and source TESTING/LIN/dchkab.f(3); it didn’t show a calendar date, so I’m not inventing one 🌈💅
