gaussian This function returns a Gaussian convolution window. w = gaussian (m) w = gaussian (m, a) m: positive integer value a: w: output variable, vector of real numbers 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.
