s = s1.train;
y0 = datasample(s,1);
y = y0(1:5000);
g = heog_1;
g = g(1:5000);
x = y+g;
% first 5000 samples
figure; p=plot(y);
hold on;
plot(g);
plot(x,'black');

[imf,residual,info] = emd(y0,'Interpolation','pchip'); %%There is an error
figure;hht(imf,5000)

Whenever you mention an error in the forum, attach a copy of the complete error message. It is much easier to fix an error than to guess, what the error is.

Hi Komal,
I suggest you share the complete error message for better diagnosis. Based on my observations, you can check the following steps:
1.Ensure the Signal Processing Toolbox is installed:
ver signal
2. Check that y0 is a numeric vector:
disp(class(y0));
disp(size(y0));
3. Verify the correct use of emd function:
[imf, residual, info] = emd(y0, 'Interpolation', 'pchip');
If you still encounter an error, please provide the complete error message for further assistance.
