I have a bunch of data that looks like a noisy square wave (more like a
trapazoid actually, with it wider on the bottom) and I've been trying to
find a consistent way to find the hight and width. I first fit a gaussian
using NonlinearFit, but that tended to have its center shift, even if I only
multiplied the raw data by a constant. I tried fitting to an actual square
wave using a step function, but that didn't give me a good result either.
Any ideas? Thanks so much.
