N

```          N is INTEGER
The number of columns of the matrices A and B.  N >= 0.```

A

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

AF

`          AF is COMPLEX array, dimension (LDA,N)`

LDA

```          LDA is INTEGER
The leading dimension of the arrays A, AF, Q and R.

The P-by-N matrix A.```

BF

`          BF is COMPLEX array, dimension (LDB,N)`

LDB

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

C

```          C is COMPLEX array, dimension( M )
the vector C in the LSE problem.```

CF

`          CF is COMPLEX array, dimension( M )`

D

```          D is COMPLEX array, dimension( P )
the vector D in the LSE problem.```

DF

X

```          X is COMPLEX array, dimension( N )
solution vector X in the LSE problem.```

WORK

`          WORK is COMPLEX array, dimension (LWORK)`

LWORK

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

RWORK

`          RWORK is REAL array, dimension (M)`

RESULT

```          RESULT is REAL array, dimension (2)
The test ratios:
RESULT(1) = norm( A*x - c )/ norm(A)*norm(X)*EPS
RESULT(2) = norm( B*x - d )/ norm(B)*norm(X)*EPS```
