WebOct 1, 2024 · Hello Everyone, Actually, I have a curve which is a result of an experiment ( the black curve in below picture). I need to find some gaussian ( or other function) to fit to this diagram in the following way (The red curves). The idea, is that the main curve has some bumbs and I need to fit some ideal curves to the main curve. WebMar 25, 2024 · Edited: Matt J on 17 Mar 2024. Use the cftool to export each fit to a workspace variable cfit1 and cfit2. Then. Theme. Copy. plot (cfit1,Varname1,y); hold on. plot (cfit2,Varname1,y1); hold off. Matt J. @Carlos Eduardo Correia Gatell I'm glad it worked, but if so, please Accept-click the Answer.
