+	* Calculates the k-th discrete forward difference of a one-dimensional double-precision floating-point ndarray.
+	*
+	* ## Notes
+	*
+	* -   The function expects the following ndarrays:
+	*
+	*     -   a one-dimensional input ndarray.
+	*     -   a one-dimensional ndarray containing values to prepend.
+	*     -   a one-dimensional ndarray containing values to append.
+	*     -   a one-dimensional output ndarray.
+	*     -   a one-dimensional workspace ndarray.
+	*     -   a zero-dimensional ndarray specifying the number of times to recursively compute differences.
+	*
+	* @param arrays - array-like object containing ndarrays
+	* @returns output ndarray
+	*
+	* @example
+	* var Float64Vector = require( '@stdlib/ndarray-vector-float64' );
+	* var scalar2ndarray = require( '@stdlib/ndarray-from-scalar' );
+	*
+	* var x = new Float64Vector( [ 2.0, 4.0, 6.0, 8.0, 10.0 ] );
+	* var prepend = new Float64Vector( [ 1.0 ] );
+	* var append = new Float64Vector( [ 11.0 ] );
+	* var out = new Float64Vector( 6 );
+	* var workspace = new Float64Vector( 6 );
+	* var k = scalar2ndarray( 1, {
+	*     'dtype': 'generic'
+	* });
+	*
+	* var y = ns.ddiff( [ x, prepend, append, out, workspace, k ] );
