💖 TESTING/LI...a_2stage.f(3) 💖

okay so bestie, welcome to the Library Functions Manual page for TESTING/LI...a_2stage.f(3) — it’s giving LAPACK test-driver main character energy, and we’re gonna read it together without missing a single detail 💅✨

💅 Function/Subroutine Documentation 💅

       subroutine sdrvsy_aa_2stage (logical, dimension( * ) dotype, integer nn,
           integer, dimension( * ) nval, integer nrhs, real thresh, logical tsterr,
           integer nmax, real, dimension( * ) a, real, dimension( * ) afac, real,
           dimension( * ) ainv, real, dimension( * ) b, real, dimension( * ) x,
           real, dimension( * ) xact, real, dimension( * ) work, real, dimension( *
           ) rwork, integer, dimension( * ) iwork, integer nout)
           SDRVSY_AA_2STAGE

🎯 Purpose 🎯

okay so the assignment is literally this: SDRVSY_AA_2STAGE tests the driver routine SSYSV_AA_2STAGE. that’s the whole vibe, no cap 🫶

🍓 Parameters 🍓

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). these are the matrix types used for testing. matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
• NN — NN is INTEGER. it’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is an INTEGER array, dimension (NN). it holds the values of the matrix dimension N.
• NRHS — NRHS is INTEGER. it’s the number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is REAL. it’s 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 — TSTERR is LOGICAL. it’s the flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. it’s the maximum value permitted for N, used in dimensioning the work arrays.
• A — A is a REAL array, dimension (NMAX*NMAX).
• AFAC — AFAC is a REAL array, dimension (NMAX*NMAX).
• AINV — AINV is a REAL array, dimension (NMAX*NMAX).
• B — B is a REAL array, dimension (NMAX*NRHS).
• X — X is a REAL array, dimension (NMAX*NRHS).
• XACT — XACT is a REAL array, dimension (NMAX*NRHS).
• WORK — WORK is a REAL array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is a REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is an INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. it’s the unit number for output.
