I am using the built in function emd(x), but I can't get the time periode I used for the signal, instead there are samples on the x-axis.
Can anyone help me with assigning time vector on the x-axis for emd?
Thanks in advance,

hello
if you know your sampling frequency (Fs) of the original data , and the length of the data , it's fairly straithforward :
dt = 1/Fs;
time = (0:samples-1) * dt;

hello Jan
I thought the topic has already been answered - in another post (about the same exact question ??)
