*
* =========== DOCUMENTATION ===========
*
* Online html documentation available at
* http://www.netlib.org/lapack/explore-html/
*
* Definition:
* ===========
*
* SUBROUTINE CCHKUNHR_COL( THRESH, TSTERR, NM, MVAL, NN, NVAL, NNB,
* NBVAL, NOUT )
*
* .. Scalar Arguments ..
* LOGICAL TSTERR
* INTEGER NM, NN, NNB, NOUT
* REAL THRESH
* ..
* .. Array Arguments ..
* INTEGER MVAL( * ), NBVAL( * ), NVAL( * )
*
*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> CCHKUNHR_COL tests:
*> 1) CUNGTSQR and CUNHR_COL using CLATSQR, CGEMQRT,
*> 2) CUNGTSQR_ROW and CUNHR_COL inside CGETSQRHRT
*> (which calls CLATSQR, CUNGTSQR_ROW and CUNHR_COL) using CGEMQRT.
*> Therefore, CLATSQR (part of CGEQR), CGEMQRT (part of CGEMQR)
*> have to be tested before this test.
*>
*> \endverbatim
*
* Arguments:
* ==========
*
*> \param[in] THRESH
*> \verbatim
*> 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.
*> \endverbatim
*>
*> \param[in] TSTERR
*> \verbatim
*> TSTERR is LOGICAL
*> Flag that indicates whether error exits are to be tested.
*> \endverbatim
*>
*> \param[in] NM
*> \verbatim
*> NM is INTEGER
*> The number of values of M contained in the vector MVAL.
*> \endverbatim
*>
*> \param[in] MVAL
*> \verbatim
*> MVAL is INTEGER array, dimension (NM)
*> The values of the matrix row dimension M.
*> \endverbatim
*>
*> \param[in] NN
*> \verbatim
*> NN is INTEGER
*> The number of values of N contained in the vector NVAL.
*> \endverbatim
*>
*> \param[in] NVAL
*> \verbatim
*> NVAL is INTEGER array, dimension (NN)
*> The values of the matrix column dimension N.
*> \endverbatim
*>
*> \param[in] NNB
*> \verbatim
*> NNB is INTEGER
*> The number of values of NB contained in the vector NBVAL.
*> \endverbatim
*>
*> \param[in] NBVAL
*> \verbatim
*> NBVAL is INTEGER array, dimension (NNB)
*> The values of the blocksize NB.
*> \endverbatim
*>
*> \param[in] NOUT
*> \verbatim
*> NOUT is INTEGER
*> The unit number for output.
