<div class="refsection"><h3 class="title">Description</h3>
<p class="para">This is an Octave function.
This function returns the filter coefficients of a Blackman-Harris 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.</p></div>
