and i want to using SHANNON ENERGY ENVELOPE for it

but i didnt find the code for it, in 'envelope' documentation there is only peak,rms and analytic function

is there any way to use the shannon energy envelope ?

thank you so much

Shannon energy is defined as

, so use an anonymous function such as:

ShannonEnergy = @(x) x.^2 .* log(x.^2);

and then take the peak envelope.

That is what I would do.
