p1.mat
t.mat

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])

Hi, just wanted to know what does .ans do in the code?

.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.
