Purpose:

 CSRSCL 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.
 

Parameters:

[in]	N	N is INTEGER The number of components of the vector x.
[in]	SA	SA is REAL The scalar a which is used to divide each component of x. SA must be >= 0, or the subroutine will divide by zero.
[in,out]	SX	SX is COMPLEX array, dimension (1+(N-1)*abs(INCX)) The n-element vector x.
[in]	INCX	INCX is 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
