How to smoothen the signal and make a good envelope

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?

[Ramesh Bala]

.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.
