NettetThis example uses the filter function to compute averages along a vector of data. Create a 1-by-100 row vector of sinusoidal data that is corrupted by random noise. t = linspace(-pi,pi,100); rng default %initialize random number generator x = sin(t) + 0.25*rand(size(t)); A moving-average filter slides a window of length windowSize along the ... NettetThis can be done by convolving with a sequence of np.ones of a length equal to the sliding window length we want. In order to do so we could define the following function: def moving_average (x, w): return np.convolve (x, np.ones (w), 'valid') / w This function will be taking the convolution of the sequence x and a sequence of ones of length w.
