🌈 Parameters 🌈

DOTYPE

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 — the number of values of N contained in the vector NVAL.

NVAL

NVAL is INTEGER array, dimension (NN) — the values of the matrix column dimension N.

NRHS

NRHS is INTEGER — the number of right hand side vectors to be generated for each linear system.

THRESH

THRESH is 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

TSTERR is LOGICAL — flag that indicates whether error exits are to be tested.

A

A is COMPLEX array, dimension (LA).

LA

LA is INTEGER — the length of the array A. LA >= (2*NMAX-1)*NMAX where NMAX is the largest entry in NVAL.

AFB

AFB is COMPLEX array, dimension (LAFB).

LAFB

LAFB is INTEGER — the length of the array AFB. LAFB >= (3*NMAX-2)*NMAX where NMAX is the largest entry in NVAL.

ASAV

ASAV is COMPLEX array, dimension (LA).

B

B is COMPLEX array, dimension (NMAX*NRHS).

BSAV

BSAV is COMPLEX array, dimension (NMAX*NRHS).

X

X is COMPLEX array, dimension (NMAX*NRHS).

XACT

XACT is COMPLEX array, dimension (NMAX*NRHS).

S

S is REAL array, dimension (2*NMAX).

WORK

WORK is COMPLEX array, dimension (NMAX*max(3,NRHS,NMAX)).

RWORK

RWORK is REAL array, dimension (max(2*NMAX,NMAX+2*NRHS)).

IWORK

IWORK is INTEGER array, dimension (NMAX).

NOUT

NOUT is INTEGER — the unit number for output.
