SCHKPS

Purpose:

` SCHKPS tests SPSTRF.`
Parameters

DOTYPE

```          DOTYPE is LOGICAL array, dimension (NTYPES)
The matrix types to be used for testing.  Matrices of type j
(for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
.TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.```

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 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 block size NB.```

NRANK

```          NRANK is INTEGER
The number of values of RANK contained in the vector RANKVAL.```

RANKVAL

```          RANKVAL is INTEGER array, dimension (NBVAL)
The values of the block size NB.```

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.```

NMAX

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

A

`          A is REAL array, dimension (NMAX*NMAX)`

AFAC

`          AFAC is REAL array, dimension (NMAX*NMAX)`

PERM

`          PERM is REAL array, dimension (NMAX*NMAX)`

PIV

`          PIV is INTEGER array, dimension (NMAX)`

WORK

`          WORK is REAL array, dimension (NMAX*3)`

RWORK

`          RWORK is REAL array, dimension (NMAX)`

NOUT

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