I have a velocity and time data.I would like to smoothen the signal as the hilbert of the signal is very dense ? How to do it
filenames= ["p1"]; % 0 degrees
for k=1:numel(filenames)
s(k)=load (filenames{k});
signal(k,1:length(s(k).ans))=s(k).ans;
end
load('t.mat')
figure;
plot(t,(signal(k,:)),t,envelope(signal(k,:)),time4(k),a6(k),'ro');
hold on
grid on;xlim([0 8E-4])
ylim([-inf inf])

.ans is just the extension of the variable Stored as such. It has nothing to do in the code

You can try doing this interactievly using the new Smooth Data task. You can test out a variety of settings to see what works with your data. See here for more info.
Consider going through this video from our course on Coursera to see if it helps you out as well.
