*  =============
*>
*> \verbatim
*>
*> ZGBEQU computes row and column scalings intended to equilibrate an
*> M-by-N band matrix A and reduce its condition number.  R returns the
*> row scale factors and C the column scale factors, chosen to try to
*> make the largest element in each row and column of the matrix B with
*> elements B(i,j)=R(i)*A(i,j)*C(j) have absolute value 1.
*>
*> R(i) and C(j) are restricted to be between SMLNUM = smallest safe
*> number and BIGNUM = largest safe number.  Use of these scaling
*> factors is not guaranteed to reduce the condition number of A but
*> works well in practice.
