How to use envelope function in Matlab?

Description. [ yupper,ylower ] = envelope( x ) returns the upper and lower envelopes of the input sequence, x , as the magnitude of its analytic signal. The analytic signal of x is found using the discrete Fourier transform as implemented in hilbert .

How do you find the Hilbert transform in Matlab?

x = hilbert( xr ) returns the analytic signal, x , from a real data sequence, xr . If xr is a matrix, then hilbert finds the analytic signal corresponding to each column. x = hilbert( xr , n ) uses an n -point fast Fourier transform (FFT) to compute the Hilbert transform.

What is Hilbert envelope?

The envelope is the magnitude of the analytic signal computed by hilbert . Plot the envelope along with the original signal. Store the name-value pair arguments of the plot function in a cell array for later use.
