+	* Multiplies a one-dimensional double-precision complex floating-point ndarray by a scalar constant.
+	*
+	* ## Notes
+	*
+	* -   The function expects the following ndarrays:
+	*
+	*     -   a one-dimensional input ndarray.
+	*     -   a zero-dimensional ndarray containing a scalar constant.
+	*
+	* @param arrays - array-like object containing ndarrays
+	* @returns input ndarray
+	*
+	* @example
+	* var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
+	* var Complex128 = require( '@stdlib/complex/float64/ctor' );
+	* var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
