NAME
CLASCL  multiplies 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

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.
= aqGaq: A is a full matrix.
= aqLaq: A is a lower triangular matrix.
= aqUaq: A is an upper triangular matrix.
= aqHaq: A is an upper Hessenberg matrix.
= aqBaq: A is a symmetric band matrix with lower bandwidth KL
and upper bandwidth KU and with the only the lower
half stored.
= aqQaq: A is a symmetric band matrix with lower bandwidth KL
and upper bandwidth KU and with the only the upper
half stored.
= aqZaq: 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 = aqBaq,
aqQaq or aqZaq.
 KU (input) INTEGER

The upper bandwidth of A. Referenced only if TYPE = aqBaq,
aqQaq or aqZaq.
 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,N)

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 ith argument had an illegal value.
