ZCHKTR

Purpose:

ZCHKTR tests ZTRTRI, -TRS, -RFS, and -CON, and ZLATRS(3)
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.

NNB

NNB is INTEGER
The number of values of NB contained in the vector NBVAL.

NBVAL

NBVAL is INTEGER array, dimension (NNB)
The values of the blocksize NB.

NNS

NNS is INTEGER
The number of values of NRHS contained in the vector NSVAL.

NSVAL

NSVAL is INTEGER array, dimension (NNS)
The values of the number of right hand sides NRHS.

THRESH

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
Flag that indicates whether error exits are to be tested.

NMAX

NMAX is INTEGER
The leading dimension of the work arrays.
NMAX >= the maximum value of N in NVAL.

A

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

AINV

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

B

B is COMPLEX*16 array, dimension (NMAX*NSMAX)
where NSMAX is the largest entry in NSVAL.

X

X is COMPLEX*16 array, dimension (NMAX*NSMAX)

XACT

XACT is COMPLEX*16 array, dimension (NMAX*NSMAX)

WORK

WORK is COMPLEX*16 array, dimension
(NMAX*max(3,NSMAX))

RWORK

RWORK is DOUBLE PRECISION array, dimension
(max(NMAX,2*NSMAX))

NOUT

NOUT is INTEGER
The unit number for output.
