SCHKTZ

Purpose:

    !>
    !> SCHKTZ tests STZRZF.
    !>

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.
    !>

    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.
    !>

    A

    !>          A is REAL array, dimension (MMAX*NMAX)
    !>          where MMAX is the maximum value of M in MVAL and NMAX is the
    !>          maximum value of N in NVAL.
    !>

    COPYA

    !>          COPYA is REAL array, dimension (MMAX*NMAX)
    !>

    S

    !>          S is REAL array, dimension
    !>                      (min(MMAX,NMAX))
    !>

    TAU

    !>          TAU is REAL array, dimension (MMAX)
    !>

    WORK

    !>          WORK is REAL array, dimension
    !>                      (MMAX*NMAX + 4*NMAX + MMAX)
    !>

    NOUT

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