DCHKSY_AA

Purpose:

    !>
    !> DCHKSY_AA tests DSYTRF_AA, -TRS_AA.
    !>

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

    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)

    !>

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

    A

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

    AFAC

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