How do I make my Matlab curve smoother?

Fit smoothing splines in the Curve Fitter app or with the fit function to create a smooth curve through data and specify the smoothness. Fit smooth surfaces to your data in the Curve Fitter app or with the fit function using Lowess models.

How to make an envelope in Matlab?

Use a Hilbert filter with a length of 100. Plot the channels and the envelopes. Use solid lines for the upper envelopes and dashed lines for the lower envelopes. Call envelope without output arguments to produce a plot of the signal and its envelopes as a function of sample number.

How to use envelope detector in Matlab?

You find the envelope of the signal by taking the absolute value of the analytic signal. The envelope is a low frequency signal compared to the original signal. To reduce its sampling frequency, to eliminate ringing and to smooth the envelope, you downsample this signal and pass the result through a lowpass filter.

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.
