Hi, I'm trying to extract features from an EEG; I've not too much experience in Matlab, so I don't really know how to proceed. Could someone help?

You would want to extract the frequency components of your signal using either Fourier transforms or Wavelet approaches. This is a good start.
Best, Sandro

Hello Chiara,
If you want to extract the alpha and theta rhythm of the signal, you can find the wigner-ville transform of the signal (from which you can easily see the frequency band of the signal at any time point). This can actually help. A built-in function of this is not available in MATLAB but there are toolboxes which are supported in MATLAB. Below are two toolboxes for this:
