 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.

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.
