CDRVPP

Purpose:

` CDRVPP tests the driver routines CPPSV and -SVX.`
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.```

NRHS

```          NRHS is INTEGER
The number of right hand side vectors to be generated for
each linear system.```

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+1)/2)`

AFAC

`          AFAC is COMPLEX array, dimension (NMAX*(NMAX+1)/2)`

ASAV

`          ASAV is COMPLEX array, dimension (NMAX*(NMAX+1)/2)`

B

`          B is COMPLEX array, dimension (NMAX*NRHS)`

BSAV

`          BSAV is COMPLEX array, dimension (NMAX*NRHS)`

X

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

XACT

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

S

`          S is REAL array, dimension (NMAX)`

WORK

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

RWORK

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

NOUT

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