NAME
       SRC/dlascl.f

SYNOPSIS
   Functions/Subroutines
       subroutine dlascl (type, kl, ku, cfrom, cto, m, n, a, lda, info)
           DLASCL multiplies a general rectangular matrix by a real scalar
           defined as cto/cfrom.

Function/Subroutine Documentation
   subroutine dlascl (character type, integer kl, integer ku, double precision
       cfrom, double precision cto, integer m, integer n, double precision,
       dimension( lda, * ) a, integer lda, integer info)
       DLASCL multiplies a general rectangular matrix by a real scalar defined
       as cto/cfrom.

       Purpose:


            DLASCL 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.

       Parameters
           TYPE

                     TYPE is 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. See DGBTRF for storage details.

           KL

                     KL is INTEGER
                     The lower bandwidth of A.  Referenced only if TYPE = 'B',
                     'Q' or 'Z'.

           KU

                     KU is INTEGER
                     The upper bandwidth of A.  Referenced only if TYPE = 'B',
                     'Q' or 'Z'.

           CFROM

                     CFROM is DOUBLE PRECISION

           CTO

                     CTO is 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

                     M is INTEGER
                     The number of rows of the matrix A.  M >= 0.

           N

                     N is INTEGER
                     The number of columns of the matrix A.  N >= 0.

           A

                     A is DOUBLE PRECISION array, dimension (LDA,N)
                     The matrix to be multiplied by CTO/CFROM.  See TYPE for the
                     storage type.

           LDA

                     LDA is INTEGER
                     The leading dimension of the array A.
                     If TYPE = 'G', 'L', 'U', 'H', LDA >= max(1,M);
                        TYPE = 'B', LDA >= KL+1;
                        TYPE = 'Q', LDA >= KU+1;
                        TYPE = 'Z', LDA >= 2*KL+KU+1.

           INFO

                     INFO is INTEGER
                     0  - successful exit
                     <0 - if INFO = -i, the i-th argument had an illegal value.
