ZLASCL(l)					)					ZLASCL(l)

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

SYNOPSIS
       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, * )

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/under-
       flow. TYPE specifies that A may be full, upper triangular, lower triangular, upper Hessen-
       berg, 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.
