Function/Subroutine Documentation
subroutine zchktr (logical, dimension( * ) dotype, integer nn, integer, dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer nns, integer, dimension( * ) nsval, double precision thresh, logical tsterr, integer nmax, complex*16, dimension( * ) a, complex*16, dimension( * ) ainv, complex*16, dimension( * ) b, complex*16, dimension( * ) x, complex*16, dimension( * ) xact, complex*16, dimension( * ) work, double precision, dimension( * ) rwork, integer nout)
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.
