ZDRSCL(3)                  MathKeisan LAPACK routine                 ZDRSCL(3)



NAME
       ZDRSCL - an n-element complex vector x by the real scalar 1/a

SYNOPSIS
       SUBROUTINE ZDRSCL( N, SA, SX, INCX )

           INTEGER        INCX, N

           DOUBLE         PRECISION SA

           COMPLEX*16     SX( * )

PURPOSE
       ZDRSCL multiplies an n-element complex vector x by the real scalar 1/a.
       This is done without overflow or underflow as long as the final  result
       x/a does not overflow or underflow.


ARGUMENTS
       N       (input) INTEGER
               The number of components of the vector x.

       SA      (input) DOUBLE PRECISION
               The  scalar  a which is used to divide each component of x.  SA
               must be >= 0, or the subroutine will divide by zero.

       SX      (input/output) COMPLEX*16 array, dimension
               (1+(N-1)*abs(INCX)) The n-element vector x.

       INCX    (input) INTEGER
               The increment between successive values of the vector SX.  > 0:
               SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i),     1< i<= n
