+	* Computes the forward discrete Fourier transform (DFT) of a real-valued one-dimensional double-precision floating-point ndarray.

+	* ## Notes
+	*
+	* -   The function expects the following ndarrays:
+	*
+	*     -   a one-dimensional input ndarray.
+	*     -   a one-dimensional workspace ndarray containing pre-computed values.
+	*
+	* @param arrays - array-like object containing ndarrays
+	* @returns input ndarray
+	*
+	* @example
+	* var Float64Vector = require( '@stdlib/ndarray/vector/float64' );
+	* var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+	* var rffti = require( '@stdlib/fft/base/fftpack/ndarray/float64/rffti' );
+	*
+	* var N = 4;
+	* var len = scalar2ndarray( N, {
+	*     'dtype': 'int32'
+	* });
+	*
+	* var w = new Float64Vector( ( 2*N ) + 34 );
+	* rffti( [ w, len ] );
+	*
+	* var r = new Float64Vector( [ 1.0, 2.0, 3.0, 4.0 ] );
+	*
+	* var out = ns.rfftf( [ r, w ] );
+	* // returns <ndarray>[ 10.0, -2.0, 2.0, -2.0 ]
+	*
+	* var bool = ( out === r );
+	* // returns true
