🌸 SDRVSP(3) — NAME 🌸

hey bestie, welcome to SDRVSP(3) from the Library Functions Manual 💖 the header path was /home/abui...IN/sdrvsp.f(3), and this whole page is about this exact file:

    SDRVSP

yep, that’s the name again: SDRVSP ✨

🌟 Purpose 🌟

okay so the whole vibe is: SDRVSP tests the driver routines SSPSV and -SVX. periodt 💅

🫶 Parameters 🫶

• DOTYPE — LOGICAL array, dimension (NTYPES). this is the matrix-type menu 🍓 matrices of type j (for 1 <= j <= NTYPES) get tested if 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). these are the values of the matrix dimension N 🎀
• NRHS — INTEGER. how many right hand side vectors get generated for each linear system.
• THRESH — REAL. the threshold value for the test ratios. a result gets included in the output file if RESULT >= THRESH. if you want 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*NRHS).
• X — REAL array, dimension (NMAX*NRHS).
• XACT — REAL array, dimension (NMAX*NRHS).
• WORK — REAL array, dimension (NMAX*max(2,NRHS)).
• RWORK — REAL array, dimension (NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. the unit number for output 🖨️
