SCHKSY

Purpose:

!>
!> SCHKSY tests SSYTRF, -TRI2, -TRS, -TRS2, -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.
!>

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 REAL
!>          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 maximum value permitted for N, used in dimensioning the
!>          work arrays.
!>

A

!>          A is REAL array, dimension (NMAX*NMAX)
!>

AFAC

!>          AFAC is REAL array, dimension (NMAX*NMAX)
!>

AINV

!>          AINV is REAL array, dimension (NMAX*NMAX)
!>

B

!>          B is REAL array, dimension (NMAX*NSMAX)
!>          where NSMAX is the largest entry in NSVAL.
!>

X

!>          X is REAL array, dimension (NMAX*NSMAX)
!>

XACT

!>          XACT is REAL array, dimension (NMAX*NSMAX)
!>

WORK

!>          WORK is REAL array, dimension (NMAX*max(3,NSMAX))
!>

RWORK

!>          RWORK is REAL array, dimension (max(NMAX,2*NSMAX))
!>

IWORK

!>          IWORK is INTEGER array, dimension (2*NMAX)
!>

NOUT

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