ZSCAL

Purpose:

    ZSCAL scales a vector by a constant.

Parameters

[in]	N	N is INTEGER number of elements in input vector(s)
[in]	ZA	ZA is COMPLEX*16 On entry, ZA specifies the scalar alpha.
[in,out]	ZX	ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
[in]	INCX	INCX is INTEGER storage spacing between elements of ZX
