WebFeb 26, 2024 · I used Curve Fitting Toolbox on three data sets of my data, used Smoothing Spline and excluded a lot of point to smooth the graphs a little. I generated a code for all free fitted curves and now I would like to get all three plots into one figure. I used the last section to PLOT ALL to plot all three fitresults but it gives me the following error. WebJun 11, 2024 · The only spline inside fit where any form of approximation to your data arises is in the smoothing spline, and you have not asked about that one. But remember that ANYTHING that is explicitly called interpolation will always predict the data with essentially no error. An interpolant is only worried about what it will do BETWEEN the data points.
