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

SYNOPSIS
       SUBROUTINE CLASCL( TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO )

	   CHARACTER	  TYPE

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

	   REAL 	  CFROM, CTO

	   COMPLEX	  A( LDA, * )

PURPOSE
       CLASCL 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) REAL
	       CTO	(input)  REAL  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 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.
