CCHKPO

Purpose:

` CCHKPO tests CPOTRF, -TRI, -TRS, -RFS, and -CON`
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 blocksize NB.```

NNS

```          NNS is INTEGER
The number of values of NRHS contained in the vector NSVAL.```

NSVAL

```          NSVAL is INTEGER array, dimension (NNS)
The values of the number of right hand sides NRHS.```

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 COMPLEX array, dimension (NMAX*NMAX)`

AFAC

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

AINV

`          AINV is COMPLEX array, dimension (NMAX*NMAX)`

B

```          B is COMPLEX array, dimension (NMAX*NSMAX)
where NSMAX is the largest entry in NSVAL.```

X

`          X is COMPLEX array, dimension (NMAX*NSMAX)`

XACT

`          XACT is COMPLEX array, dimension (NMAX*NSMAX)`

WORK

```          WORK is COMPLEX array, dimension
(NMAX*max(3,NSMAX))```

RWORK

```          RWORK is REAL array, dimension
(NMAX+2*NSMAX)```

NOUT

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