+	*
+	* -   The function expects the following ndarrays:
+	*
+	*     -   first one-dimensional input ndarray.
+	*     -   second one-dimensional input ndarray.
+	*
+	* @param arrays - array-like object containing ndarrays
+	* @returns second input ndarray

+	* var x = vector( [ 1.0, 2.0, 3.0, 4.0, 5.0 ], 'generic' );
