CCHKHP

Purpose:

CCHKHP tests CHPTRF, -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.

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+1)/2)

AFAC

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

AINV

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

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(2,NSMAX))

RWORK

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

IWORK

IWORK is INTEGER array, dimension (NMAX)

NOUT

NOUT is INTEGER
The unit number for output.
