NAME

        ZDRSCL - multiplie 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:
X(1) and SX(1+(i-1)*INCX) = x(i),     1< i<= n
