Purpose:

 DLA_GESYLV solves a Sylvester equation of the following forms

    op1(A) * X  +  X * op2(B) = SCALE * Y                              (1)

 or

    op1(A) * X  -  X * op2(B) = SCALE * Y                              (2)

 where A is a M-by-M matrix and B is a N-by-N matrix. The right hand
 side Y and the solution X are M-by-N matrices. The matrices A and B can be
 either a general unreduced matrix or a (quasi-) upper triangular factor.
 In the later case QA and QB provide the Schur-vectors of the matrices A
 and B.

    op1(A) * X  -  X * op2(B) = Y                              (2)

 where A is a M-by-M matrix and B is a N-by-N matrix using iterative refinement.
 The right hand side Y and the solution X are M-by-N matrices.
 The matrix A and B need to be given in the original form as well
 as in their Schur decomposition since both are required in the
 iterative refinement procedure.
