ZLASCL 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.

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 ZGBTRF 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 COMPLEX*16 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.
