## Function/Subroutine Documentation

### subroutine dcklse (integer nn, integer, dimension( * ) mval, integer, dimension( * ) pval, integer, dimension( * ) nval, integer nmats, integer, dimension( 4 ) iseed, double precision thresh, integer nmax, double precision, dimension( * ) a, double precision, dimension( * ) af, double precision, dimension( * ) b, double precision, dimension( * ) bf, double precision, dimension( * ) x, double precision, dimension( * ) work, double precision, dimension( * ) rwork, integer nin, integer nout, integer info)

DCKLSE

Purpose:

``` DCKLSE tests DGGLSE - a subroutine for solving linear equality
constrained least square problem (LSE).```
Parameters

NN

```          NN is INTEGER
The number of values of (M,P,N) contained in the vectors
(MVAL, PVAL, NVAL).```

MVAL

```          MVAL is INTEGER array, dimension (NN)
The values of the matrix row(column) dimension M.```

PVAL

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

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.```

A

`          A is DOUBLE PRECISION array, dimension (NMAX*NMAX)`

AF

`          AF is DOUBLE PRECISION array, dimension (NMAX*NMAX)`

B

`          B is DOUBLE PRECISION array, dimension (NMAX*NMAX)`

BF

`          BF is DOUBLE PRECISION array, dimension (NMAX*NMAX)`

X

`          X is DOUBLE PRECISION array, dimension (5*NMAX)`

WORK

`          WORK is DOUBLE PRECISION array, dimension (NMAX*NMAX)`

RWORK

`          RWORK is DOUBLE PRECISION array, dimension (NMAX)`

NIN

```          NIN is INTEGER
The unit number for input.```

NOUT

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

INFO

```          INFO is INTEGER
= 0 :  successful exit
> 0 :  If DLATMS returns an error code, the absolute value
of it is returned.```
