I have a plot generated from an ugly and complex set of piece-wise functions. I'm looking to extract the envelope function from this data set. I've tried a lot of suggestions in other threads, but none seem to contain information about dealing with piece-wise functions. I've tried using a Fourier series, but that didn't seem to give me what I was looking for. The plot is located below

- $\begingroup$ Try a MaxFilter with a window about 2 or 3 units wide to extract the upper envelope. MinFilter will get the lower envelope, though from the look of your graph, this may not be interesting. $\endgroup$bill s– bill s2018-11-12 04:56:03 +00:00Commented Nov 12, 2018 at 4:56
