ZCHKUNHR_COL

Purpose:
 ZCHKUNHR_COL tests:
   1) ZUNGTSQR and ZUNHR_COL using ZLATSQR, ZGEMQRT,
   2) ZUNGTSQR_ROW and ZUNHR_COL inside ZGETSQRHRT
      (which calls ZLATSQR, ZUNGTSQR_ROW and ZUNHR_COL) using ZGEMQRT.
 Therefore, ZLATSQR (part of ZGEQR), ZGEMQRT (part of ZGEMQR)
 have to be tested before this test.
Parameters
[in]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.
[in]TSTERR
          TSTERR is LOGICAL
          Flag that indicates whether error exits are to be tested.
[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]NNB
          NNB is INTEGER
          The number of values of NB contained in the vector NBVAL.
[in]NBVAL
          NBVAL is INTEGER array, dimension (NNB)
          The values of the blocksize NB.
[in]NOUT
          NOUT is INTEGER
          The unit number for output.
