Hello everyone, I was wondering if anyone knows how I could process the input data in such a way as to obtain something similar to what I show in smooth data. The points marked in red and blue correspond to the change points when using the ischange tool
cI = ischange(YY,'MaxNumChanges',1);
I include an attached data with the points shown in the graph being XX and YY the input data (the ones I intend to modify) and the XSmooth, YSmooth data the ones I intend to get.
I've tried with the methods include in the smoothdata function but i couldn't get the result i expected
methods = {'movmean','movmedian','gaussian','lowess','loess','rlowess','rloess','sgolay'};
