ZCKGQR

Purpose:

``` ZCKGQR tests
ZGGQRF: GQR factorization for N-by-M matrix A and N-by-P matrix B,
ZGGRQF: GRQ factorization for M-by-N matrix A and P-by-N matrix B.```
Parameters

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(column) dimension M.```

NP

```          NP is INTEGER
The number of values of P contained in the vector PVAL.```

PVAL

```          PVAL is INTEGER array, dimension (NP)
The values of the matrix row(column) dimension P.```

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(row) dimension N.```

NMATS

```          NMATS is INTEGER
The number of matrix types to be tested for each combination
of matrix dimensions.  If NMATS >= NTYPES (the maximum
number of matrix types), then all the different types are
generated for testing.  If NMATS < NTYPES, another input line
is read to get the numbers of the matrix types to be used.```

ISEED

```          ISEED is INTEGER array, dimension (4)
On entry, the seed of the random number generator.  The array
elements should be between 0 and 4095, otherwise they will be
reduced mod 4096, and ISEED(4) must be odd.
On exit, the next seed in the random number sequence after
all the test matrices have been generated.```

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.```

NMAX

```          NMAX is INTEGER
The maximum value permitted for M or N, used in dimensioning
the work arrays.```
