💖 TESTING/LIN/schksp.f(3) — bestie edition 💖

okay so this is the TESTING/LIN/schksp.f(3) page from the Library Functions Manual, aka LAPACK's little corner of Unix docs. buckle up, we're checking sparse symmetric routines and it's giving main-character energy 💅

subroutine schksp (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nns, integer, dimension( * ) nsval, real
    thresh, logical tsterr, integer nmax, real, dimension( * ) a, real,

    SCHKSP

🎯 Purpose

SCHKSP tests SSPTRF, -TRI, -TRS, -RFS, and -CON — that's literally the assignment, no cap 🫡

🧾 Parameters

• DOTYPE — a LOGICAL array, dimension (NTYPES). it's the matrix-type guest list: matrix type j (for 1 <= j <= NTYPES) gets tested when DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used 💖
• NN — INTEGER. the number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). the values of the matrix dimension N 🌈
• NNS — INTEGER. the number of values of NRHS contained in the vector NSVAL.
• NSVAL — INTEGER array, dimension (NNS). the values of the number of right hand sides NRHS ✨
• THRESH — REAL. 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 👑
• TSTERR — LOGICAL. flag that indicates whether error exits are to be tested.
• NMAX — INTEGER. the maximum value permitted for N, used in dimensioning the work arrays.
• A — REAL array, dimension (NMAX*(NMAX+1)/2).
• AFAC — REAL array, dimension (NMAX*(NMAX+1)/2).
• AINV — REAL array, dimension (NMAX*(NMAX+1)/2).
• B — REAL array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• X — REAL array, dimension (NMAX*NSMAX).
• XACT — REAL array, dimension (NMAX*NSMAX).
• WORK — REAL array, dimension (NMAX*max(2,NSMAX)).
• RWORK — REAL array, dimension (NMAX+2*NSMAX).
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. the unit number for output 🎀
