I have around 1000 files, see attached graphs, and I want them to all be on the same baseline for direct comparison. I have tried the sgolayfilt with code below, however that removes a lot of features in my data as it is essentially a damping technique aswell. I was wondering if there was a baseline function that let you manually input points for fitting?
windowWidth = 101
polynomialOrder = 3
baselineY = sgolayfilt(y, polynomialOrder, windowWidth);
