## Function/Subroutine Documentation

### subroutine sckglm (integer nn, integer, dimension( * ) mval, integer, dimension( * ) pval, integer, dimension( * ) nval, integer nmats, integer, dimension( 4 ) iseed, real thresh, integer nmax, real, dimension( * ) a, real, dimension( * ) af, real, dimension( * ) b, real, dimension( * ) bf, real, dimension( * ) x, real, dimension( * ) work, real, dimension( * ) rwork, integer nin, integer nout, integer info)

**SCKGLM**

**Purpose:**

SCKGLM tests SGGGLM - subroutine for solving generalized linear model problem.

**Parameters***NN*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*A is REAL array, dimension (NMAX*NMAX)

*AF*AF is REAL array, dimension (NMAX*NMAX)

*B*B is REAL array, dimension (NMAX*NMAX)

*BF*BF is REAL array, dimension (NMAX*NMAX)

*X*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.
