SLASCL  -  multiplie  the M by N real matrix A by the real
       scalar CTO/CFROM


SYNOPSIS

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

           CHARACTER      TYPE

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

           REAL           CFROM, CTO

           REAL           A( LDA, * )


PURPOSE

       SLASCL  multiplies  the  M  by N real 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 sym­
               metric 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/under­
               flow  if  the final result CTO*A(I,J)/CFROM can be
               represented without over/underflow.  CFROM must be
               nonzero.

               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) REAL 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.
