\fBDLASCL\fP multiplies a general rectangular matrix by a real scalar defined as cto/cfrom\&.  
.PP
\fBPurpose: \fP
.RS 4

.PP
.nf
 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.

          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.

\fICTO\fP 
.PP
.nf
          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.
