## Function/Subroutine Documentation

### subroutine cchkunhr_col (real thresh, logical tsterr, integer nm, integer, dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer nout)

**CCHKUNHR_COL**

**Purpose:**

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.

**Parameters***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.

*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.

*NNB*NNB is INTEGER The number of values of NB contained in the vector NBVAL.

*NBVAL*NBVAL is INTEGER array, dimension (NNB) The values of the blocksize NB.

*NOUT*NOUT is INTEGER The unit number for output.
