DCHKAB(3)

💖 NAME 💖

okay so this is DCHKAB(3), bestie — the page lives in the Library Functions Manual, and the header/footer both point at /home/abui...IN/dchkab.f(3). The actual source file named here is /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/dchkab.f. That's the whole NAME situation. 💅

DCHKAB

Purpose

okay so DCHKAB is the test program for the DOUBLE PRECISION LAPACK DSGESV/DSPOSV routine. It absolutely 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. You can get an annotated example of a data file by deleting the first 3 characters from these 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

and these are the integer knobs from the source comment:

• 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

cute sign-off time: LAPACK Version 3.12.0, source path /home/abui...IN/dchkab.f(3) — that's the footer energy, bestie. The footer doesn't print an extra date, so no invented date here. 🫶💖
