Purpose:ZDRSCL multiplies an nelement 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. N

N is INTEGER The number of components of the vector x.SA SA is 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 SX is COMPLEX*16 array, dimension (1+(N1)*abs(INCX)) The nelement vector x.INCX INCX is INTEGER The increment between successive values of the vector SX. > 0: SX(1) = X(1) and SX(1+(i1)*INCX) = x(i), 1< i<= n Univ. of Tennessee
