PURPOSE
  ZLASCL - multiplie the M by N complex matrix A by the real scalar CTO/CFROM

SYNTAX
  SUBROUTINE ZLASCL( TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO )

      CHARACTER	     TYPE

      INTEGER	     INFO, KL, KU, LDA, M, N

      DOUBLE	     PRECISION CFROM, CTO

      COMPLEX*16     A( LDA, * )

DESCRIPTION
  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
  TYPE	  (input) 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.

  KL	  (input) INTEGER
	  The lower bandwidth of A.  Referenced only if TYPE = 'B',

  KU	  (input) INTEGER
	  The upper bandwidth of A.  Referenced only if TYPE = 'B',

  CFROM	  (input) DOUBLE PRECISION
	  CTO	  (input) 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.

  M	  (input) INTEGER
	  The number of rows of the matrix A.  M >= 0.

  N	  (input) INTEGER
	  The number of columns of the matrix A.  N >= 0.

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

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

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