DCHKGB

Purpose:

!>
!> DCHKGB tests DGBTRF, -TRS, -RFS, and -CON
!> 

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.
!> 

NM

!>          NM is INTEGER
!>          The number of values of M contained in the vector MVAL.
!> 

MVAL

!>          MVAL is INTEGER array, dimension (NM)
!>          The values of the matrix row dimension M.
!> 

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.
!> 

A

!>          A is DOUBLE PRECISION array, dimension (LA)
!> 

LA

!>          LA is INTEGER
!>          The length of the array A.  LA >= (KLMAX+KUMAX+1)*NMAX
!>          where KLMAX is the largest entry in the local array KLVAL,
!>                KUMAX is the largest entry in the local array KUVAL and
!>                NMAX is the largest entry in the input array NVAL.
!> 

AFAC

!>          AFAC is DOUBLE PRECISION array, dimension (LAFAC)
!> 

LAFAC

!>          LAFAC is INTEGER
!>          The length of the array AFAC. LAFAC >= (2*KLMAX+KUMAX+1)*NMAX
!>          where KLMAX is the largest entry in the local array KLVAL,
!>                KUMAX is the largest entry in the local array KUVAL and
!>                NMAX is the largest entry in the input array NVAL.
!> 

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)
