SCKGLM

Purpose:



 SCKGLM tests SGGGLM - subroutine for solving generalized linear


                       model problem.

Parameters



          NN is INTEGER


          The number of values of N, M and P contained in the vectors


          NVAL, MVAL and PVAL.

MVAL



          MVAL is INTEGER array, dimension (NN)


          The values of the matrix column dimension M.

PVAL



          PVAL is INTEGER array, dimension (NN)


          The values of the matrix column dimension P.

NVAL



          NVAL is INTEGER array, dimension (NN)


          The values of the matrix 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 REAL


          The threshold value for the test ratios.  A result is


          included in the output file if RESID >= 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 is REAL array, dimension (NMAX*NMAX)



          AF is REAL array, dimension (NMAX*NMAX)



          B is REAL array, dimension (NMAX*NMAX)



          BF is REAL array, dimension (NMAX*NMAX)



          X is REAL array, dimension (4*NMAX)

RWORK



          RWORK is REAL array, dimension (NMAX)

WORK



          WORK is REAL array, dimension (NMAX*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 SLATMS returns an error code, the absolute value


                 of it is returned.
