       SUBROUTINE ZLASCL( TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO )
 
       .. Scalar Arguments ..
       CHARACTER          TYPE
       INTEGER            INFO, KL, KU, LDA, M, N
       DOUBLE PRECISION   CFROM, CTO
       ..
       .. Array Arguments ..
       COMPLEX*16         A( LDA, * )
       ..
  

 Purpose:
 =============

 ZLASCL multiplies the M by N complex matrix A by the real scalar
 CTO/CFROM.  This is done without over/underflow as long as the final
 result CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that
 A may be full, upper triangular, lower triangular, upper Hessenberg,
 or banded.

 Arguments:
 ==========

  [in] TYPE

          TYPE is CHARACTER*1
          TYPE indices the storage type of the input matrix.
          = 'G':  A is a full matrix.
          = 'L':  A is a lower triangular matrix.
          = 'U':  A is an upper triangular matrix.
          = 'H':  A is an upper Hessenberg matrix.
          = 'B':  A is a symmetric band matrix with lower bandwidth KL
                  and upper bandwidth KU and with the only the lower
                  half stored.
          = 'Q':  A is a symmetric band matrix with lower bandwidth KL
                  and upper bandwidth KU and with the only the upper
                  half stored.
          = 'Z':  A is a band matrix with lower bandwidth KL and upper
                  bandwidth KU. See ZGBTRF for storage details.

  [in] KL

          KL is INTEGER
          The lower bandwidth of A.  Referenced only if TYPE = 'B',
          'Q' or 'Z'.

  [in] KU

          KU is INTEGER
          The upper bandwidth of A.  Referenced only if TYPE = 'B',
          'Q' or 'Z'.

  [in] CFROM

          CFROM is DOUBLE PRECISION

  [in] CTO

          CTO is DOUBLE PRECISION

          The matrix A is multiplied by CTO/CFROM. A(I,J) is computed
          without over/underflow if the final result CTO*A(I,J)/CFROM
          can be represented without over/underflow.  CFROM must be
          nonzero.

  [in] M

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

  [in] N

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

  [in,out] A

          A is COMPLEX*16 array, dimension (LDA,N)
          The matrix to be multiplied by CTO/CFROM.  See TYPE for the
          storage type.

  [in] LDA

          LDA is INTEGER
          The leading dimension of the array A.  LDA >= max(1,M).

  [out] INFO

          INFO is INTEGER
          0  - successful exit
          <0 - if INFO = -i, the i-th argument had an illegal value.
