Code for extracting DE (differential entropy) and PSD (power spectral density) feature of signals.
Matlab and python versions are provided.
input: data [n*m] n electrodes, m time points
stft_para.stftn frequency domain sampling rate
stft_para.fStart start frequency of each frequency band
stft_para.fEnd end frequency of each frequency band
stft_para.window window length of each sample point(seconds)
stft_para.fs original frequency
output: psd,DE [n*l*k] n electrodes, l windows, k frequency bands
