DCHKRQ

Purpose:

 DCHKRQ tests DGERQF, DORGRQ and DORMRQ.

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.

NM

          NM is INTEGER
          The number of values of M contained in the vector MVAL.

MVAL

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

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 column dimension N.

NNB

          NNB is INTEGER
          The number of values of NB and NX contained in the
          vectors NBVAL and NXVAL.  The blocking parameters are used
          in pairs (NB,NX).

NBVAL

          NBVAL is INTEGER array, dimension (NNB)
          The values of the blocksize NB.

NXVAL

          NXVAL is INTEGER array, dimension (NNB)
          The values of the crossover point NX.

NRHS

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

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.

TSTERR

          TSTERR is LOGICAL
          Flag that indicates whether error exits are to be tested.

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)

AQ

          AQ is DOUBLE PRECISION array, dimension (NMAX*NMAX)

AR

          AR is DOUBLE PRECISION array, dimension (NMAX*NMAX)

AC

          AC is DOUBLE PRECISION array, dimension (NMAX*NMAX)

B

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

X

          X is DOUBLE PRECISION array, dimension (NMAX*NRHS)

XACT

          XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS)

TAU

          TAU is DOUBLE PRECISION array, dimension (NMAX)

WORK

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

RWORK

          RWORK is DOUBLE PRECISION array, dimension (NMAX)

IWORK

          IWORK is INTEGER array, dimension (NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
