The 1st two plots are the plots of 2 imfs with highest engery content. However, according to the theory, all imfs (and hence their frqs) are plotted with respect to time. I did "hold on" and have plotted time-freq distribution for all the imfs. the plot looks kind of crowded but still gives enough information. However i still hav following questions,
1. in hilbert spectrum, in 3D plot, vertical axis amplitude is function of time. but u have obtained a single value of energy for each imf. but actually it should have been function of time.Am i right?
I have tried WIG2.m function on a times series on 28800 samples (288 sec signal sampled at 100Hz) but function doesnt seem to handle this big signal. However, I have also tried it on chunks of this signal but it takes forever to complete. Is it my computer or the program itself? any help?
I have tried using this application for a time series of 250 secs long (sampled at 100 Hz) but the application crashed Matlab. Is it the limitation of my computer or its the program? I have tried other TFA alorithms buy nothin seems to handle this long data.. it takes forever...any help us appreciated!
