SCHKTZ

Purpose:
 SCHKTZ tests STZRQF and STZRZF.
Parameters
[in]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.
[in]NM
          NM is INTEGER
          The number of values of M contained in the vector MVAL.
[in]MVAL
          MVAL is INTEGER array, dimension (NM)
          The values of the matrix row dimension M.
[in]NN
          NN is INTEGER
          The number of values of N contained in the vector NVAL.
[in]NVAL
          NVAL is INTEGER array, dimension (NN)
          The values of the matrix column dimension N.
[in]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.
[in]TSTERR
          TSTERR is LOGICAL
          Flag that indicates whether error exits are to be tested.
[out]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.
[out]COPYA
          COPYA is REAL array, dimension (MMAX*NMAX)
[out]S
          S is REAL array, dimension
                      (min(MMAX,NMAX))
[out]TAU
          TAU is REAL array, dimension (MMAX)
[out]WORK
          WORK is REAL array, dimension
                      (MMAX*NMAX + 4*NMAX + MMAX)
[in]NOUT
          NOUT is INTEGER
          The unit number for output.
