Hello, I would like to 'smooth' out the curves of these plots and plot it on top of the exisitng 'noisy' graph.

for ci= 1:length(datecell)
    figure,plot(datecell{ci},smcell{ci});
end
grid on;

Where it should look like the red curve:

I have tried using 'rmoutliers' or 'smooth' functions but they do not work, possibly due to bad coding.

Many thanks in advance.

You're looking for the fit function from the Curve Fitting Toolbox. There are some great examples on the doc page that should help you get started.
