Function/Subroutine Documentation
subroutine dchktb (logical, dimension( * ) dotype, integer nn, integer, dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double precision thresh, logical tsterr, integer nmax, double precision, dimension( * ) ab, double precision, dimension( * ) ainv, double precision, dimension( * ) b, double precision, dimension( * ) x, double precision, dimension( * ) xact, double precision, dimension( * ) work, double precision, dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
DCHKTB
Purpose:
DCHKTB tests DTBTRS, -RFS, and -CON, and DLATBS.
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.
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.
AB
AB is DOUBLE PRECISION array, dimension (NMAX*NMAX)
AINV
AINV is DOUBLE PRECISION array, dimension (NMAX*NMAX)
B
B is DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
X
X is DOUBLE PRECISION array, dimension (NMAX*NSMAX)
XACT
XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX)
WORK
WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX))
RWORK
RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX))
IWORK
IWORK is INTEGER array, dimension (NMAX)
NOUT
NOUT is INTEGER The unit number for output.
