CLASCL(3F)							    CLASCL(3F)

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.
