DCKGQR

Purpose:

!>
!> DCKGQR tests
!> DGGQRF: GQR factorization for N-by-M matrix A and N-by-P matrix B,
!> DGGRQF: GRQ factorization for M-by-N matrix A and P-by-N matrix B.
!> 

Parameters

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(column) dimension M.
!> 

NP

!>          NP is INTEGER
!>          The number of values of P contained in the vector PVAL.
!> 

PVAL

!>          PVAL is INTEGER array, dimension (NP)
!>          The values of the matrix row(column) dimension P.
!> 

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(row) dimension N.
!> 

NMATS

!>          NMATS is INTEGER
!>          The number of matrix types to be tested for each combination
!>          of matrix dimensions.  If NMATS >= NTYPES (the maximum
!>          number of matrix types), then all the different types are
!>          generated for testing.  If NMATS < NTYPES, another input line
!>          is read to get the numbers of the matrix types to be used.
!> 

ISEED

!>          ISEED is INTEGER array, dimension (4)
!>          On entry, the seed of the random number generator.  The array
!>          elements should be between 0 and 4095, otherwise they will be
!>          reduced mod 4096, and ISEED(4) must be odd.
!>          On exit, the next seed in the random number sequence after
!>          all the test matrices have been generated.
!> 

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.
!> 

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)
!> 

TAUA

!>          TAUA is DOUBLE PRECISION array, dimension (NMAX)
!> 

B

!>          B is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!> 

BF

!>          BF is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!> 

BZ

!>          BZ is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!> 

BT

!>          BT is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!> 

BWK

!>          BWK is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!> 

TAUB

!>          TAUB is DOUBLE PRECISION array, dimension (NMAX)
!> 

WORK

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

RWORK

!>          RWORK is DOUBLE PRECISION array, dimension (NMAX)
!> 

NIN

!>          NIN is INTEGER
!>          The unit number for input.
!> 

NOUT

!>          NOUT is INTEGER
!>          The unit number for output.
!> 

INFO

!>          INFO is INTEGER
!>          = 0 :  successful exit
!>          > 0 :  If DLATMS returns an error code, the absolute value
!>                 of it is returned.
