zchkunhr_col()

subroutine zchkunhr_col	(	double precision	thresh,
		logical	tsterr,
		integer	nm,
		integer, dimension( * )	mval,
		integer	nn,
		integer, dimension( * )	nval,
		integer	nnb,
		integer, dimension( * )	nbval,
		integer	nout
	)

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.
