Hey all,
I'm new to matlab, and I have to make a smoothed curve to fit the peaks of my data, similar to this picture:
I've been trying to use findpeaks(), like in this example: http://www.mathworks.com/help/toolbox/signal/ref/findpeaks.html
But I can't produce the curve like in the picture, any good ideas?
Thanks!
Donna

Maybe one of these enveloping tools could help:
however, most of the PSD envelopes I've seen are done manually, not by algorithm
