(global and local) array of size dlen_. The array descriptor for the distributed matrix A.
(local).
Array of size LOCr(m_a). The row scale factors for sub(A). r is aligned with the distributed matrix A, and replicated across every process column. r is tied to the distributed matrix A.
(local).
Array of size LOCc(n_a). The row scale factors for sub(A). c is aligned with the distributed matrix A, and replicated across every process column. c is tied to the distributed matrix A.
(local).

(global)
Specifies the form of equilibration that was done.
= 'N': No equilibration
= 'R': Row equilibration, that is, sub(A) has been pre-multiplied by diag(r[ia-1:ia+m-2]),
= 'C': column equilibration, that is, sub(A) has been post-multiplied by diag(c[ja-1:ja+n-2]),
= 'B': Both row and column equilibration, that is, sub(A) has been replaced by diag(r[ia-1:ia+m-2])* sub(A) * diag(c[ja-1:ja+n-2]).
