SGLMTS

Purpose:

``` SGLMTS tests SGGGLM - a subroutine for solving the generalized
linear model problem.```
Parameters

The number of rows of the matrices A and B.  N >= 0.```

M

```          M is INTEGER
The number of columns of the matrix A.  M >= 0.```

P

```          P is INTEGER
The number of columns of the matrix B.  P >= 0.```

A

```          A is REAL array, dimension (LDA,M)
The N-by-M matrix A.```

AF

`          AF is REAL array, dimension (LDA,M)`

LDA

```          LDA is INTEGER
The leading dimension of the arrays A, AF. LDA >= max(M,N).```

B

```          B is REAL array, dimension (LDB,P)
The N-by-P matrix A.```

BF

`          BF is REAL array, dimension (LDB,P)`

LDB

```          LDB is INTEGER
The leading dimension of the arrays B, BF. LDB >= max(P,N).```

D

```          D is REAL array, dimension( N )
On input, the left hand side of the GLM.```

DF

`          DF is REAL array, dimension( N )`

X

```          X is REAL array, dimension( M )
solution vector X in the GLM problem.```

U

```          U is REAL array, dimension( P )
solution vector U in the GLM problem.```

WORK

`          WORK is REAL array, dimension (LWORK)`

LWORK

```          LWORK is INTEGER
The dimension of the array WORK.```

RWORK

`          RWORK is REAL array, dimension (M)`

RESULT

```          RESULT is REAL
The test ratio:
norm( d - A*x - B*u )
RESULT = -----------------------------------------
(norm(A)+norm(B))*(norm(x)+norm(u))*EPS```
