December 3, 1999
Purpose
=======
ZCHKTB tests ZTBTRS, -RFS, and -CON, and ZLATBS.
Arguments
=========
DOTYPE (input) 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 (input) INTEGER
The number of values of N contained in the vector NVAL.
NVAL (input) INTEGER array, dimension (NN)
The values of the matrix column dimension N.
NNS (input) INTEGER
The number of values of NRHS contained in the vector NSVAL.
NSVAL (input) INTEGER array, dimension (NNS)
The values of the number of right hand sides NRHS.
THRESH (input) 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 (input) LOGICAL
Flag that indicates whether error exits are to be tested.
NMAX (input) INTEGER
The leading dimension of the work arrays.
NMAX >= the maximum value of N in NVAL.
AB (workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
AINV (workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
B (workspace) COMPLEX*16 array, dimension (NMAX*NSMAX)
where NSMAX is the largest entry in NSVAL.
X (workspace) COMPLEX*16 array, dimension (NMAX*NSMAX)
XACT (workspace) COMPLEX*16 array, dimension (NMAX*NSMAX)
WORK (workspace) COMPLEX*16 array, dimension
(NMAX*max(3,NSMAX))
RWORK (workspace) DOUBLE PRECISION array, dimension
(max(NMAX,2*NSMAX))
NOUT (input) INTEGER
The unit number for output.
