% error: w = gaussian(n, a) % % Generate an n-point gaussian convolution window of the given % width. Use larger a for a narrower window. Use larger n for % longer tails. % % w = exp ( -(a*x)^2/2 ) % % for x = linspace ( (n-1)/2, (n-1)/2, n ). % % Width a is measured in frequency units (sample rate/num samples). % It should be f when multiplying in the time domain, but 1/f when % multiplying in the frequency domain (for use in convolutions).
