ZDRVHE_AA_2STAGE 👑

Purpose:

!>
!> ZDRVHE_AA_2STAGE tests the driver routine ZHESV_AA_2STAGE.
!>

Parameters

• DOTYPE — okay so DOTYPE is a LOGICAL array, dimension (NTYPES). It's giving "which matrix types are we testing today" energy. Matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is literally not used. periodt 💅

!>          DOTYPE is LOGICAL array, dimension (NTYPES)
!>          The matrix types to be 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, and it's the number of values of N chillin' inside the vector NVAL. that's it, that's the whole vibe ✨

!>          NN is INTEGER
!>          The number of values of N contained in the vector NVAL.
!>

• NVAL — NVAL is an INTEGER array, dimension (NN), and it holds the values of the matrix dimension N. the actual numbers, bestie 🌸

!>          NVAL is INTEGER array, dimension (NN)
!>          The values of the matrix dimension N.
!>

• NRHS — NRHS is INTEGER and it's how many right hand side vectors get generated for each linear system. so many little right-hand sides 🫶

!>          NRHS is INTEGER
!>          The number of right hand side vectors to be generated for
!>          each linear system.
!>

• THRESH — THRESH is DOUBLE PRECISION and it's the threshold value for the test ratios. A result gets included in the output file if RESULT >= THRESH. Wanna see every single test ratio printed? Then use THRESH = 0. iconic ✨

!>          THRESH is DOUBLE PRECISION
!>          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, a lil flag that says whether error exits are gonna be tested or not 🙈

!>          TSTERR is LOGICAL
!>          Flag that indicates whether error exits are to be tested.
!>

• NMAX — NMAX is INTEGER, the maximum value permitted for N, and it's used for dimensioning the work arrays. sizing queen 👑

!>          NMAX is INTEGER
!>          The maximum value permitted for N, used in dimensioning the
!>          work arrays.
!>

• A — A is COMPLEX*16 array, dimension (NMAX*NMAX) 💜

!>          A is COMPLEX*16 array, dimension (NMAX*NMAX)
!>

• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX) 🌈

!>          AFAC is COMPLEX*16 array, dimension (NMAX*NMAX)
!>

• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX) ⭐

!>          AINV is COMPLEX*16 array, dimension (NMAX*NMAX)
!>

• B — B is COMPLEX*16 array, dimension (NMAX*NRHS) 🍓

!>          B is COMPLEX*16 array, dimension (NMAX*NRHS)
!>

• X — X is COMPLEX*16 array, dimension (NMAX*NRHS) 🧚

!>          X is COMPLEX*16 array, dimension (NMAX*NRHS)
!>

• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS) 🔥

!>          XACT is COMPLEX*16 array, dimension (NMAX*NRHS)
!>

• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(2,NRHS)). yes the max(2,NRHS) is literally in there, don't @ me 💀

!>          WORK is COMPLEX*16 array, dimension (NMAX*max(2,NRHS))
!>

• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS) 💖

!>          RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS)
!>

• IWORK — IWORK is INTEGER array, dimension (NMAX) 🦋

!>          IWORK is INTEGER array, dimension (NMAX)
!>

• NOUT — NOUT is INTEGER, the unit number for output. that's where the tea gets printed 📝

!>          NOUT is INTEGER
!>          The unit number for output.
