<div class="refsection"><h3 class="title">Description</h3>
<p class="para">This is an Octave function.
This function returns a Gaussian convolution window of length m supplied as input, to the output vector w.
The second parameter is the width measured in sample rate/number of samples and should be f for time domain and 1/f for frequency domain. The width is inversely proportional to a.</p></div>
