Function/Subroutine Documentation

subroutine DCHKPT (logical, dimension( * ) dotype, integer nn, integer, dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double precision thresh, logical tsterr, double precision, dimension( * ) a, double precision, dimension( * ) d, double precision, dimension( * ) e, double precision, dimension( * ) b, double precision, dimension( * ) x, double precision, dimension( * ) xact, double precision, dimension( * ) work, double precision, dimension( * ) rwork, integer nout)

DCHKPT

Purpose:

!>
!> DCHKPT tests DPTTRF, -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.
!>

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 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.
!>

A

!>          A is DOUBLE PRECISION array, dimension (NMAX*2)
!>

D

!>          D is DOUBLE PRECISION array, dimension (NMAX*2)
!>

E

!>          E is DOUBLE PRECISION array, dimension (NMAX*2)
!>

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))
!>

NOUT

!>          NOUT is INTEGER
!>          The unit number for output.
