+   <para>
+This is an Octave function.
+This function returns the filter coefficients of a Flat Top window of length m supplied as input, to the output vector w.
+The second parameter can take the values "periodic" or "symmetric", depending on which the corresponding form of window is returned. The default is symmetric.
+This window has low pass-band ripple but a high bandwidth.
