DCKLSE

DCKLSE

Purpose:

 DCKLSE tests DGGLSE - a subroutine for solving linear equality
 constrained least square problem (LSE).

Parameters

NN

          NN is INTEGER
          The number of values of (M,P,N) contained in the vectors
          (MVAL, PVAL, NVAL).

MVAL

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

PVAL

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

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)

B

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

BF

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

X

          X is DOUBLE PRECISION array, dimension (5*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.
