Dear Sir, I'm very impressed with the tool you've created. It was shown to me by one colleague of mine. I'm curious if you could give us a hint how to create an appropriate format in .mat file to feed the tool. E.g. I have an artificially generated signal by sine function and I could easily build a spectrum in MATLAB, how I would convert it to the appropriate format? Any scripts/hits would be greatly appreciated! Thanks, and looking forward to hearing you.
