You could probably use stdfilt() or movstd(). Try different window widths and plot the output.
Or try thresholding and labeling. Search for questions on finding words or silence in audio waveforms - there has been a lot of questions regarding that. It's a similar kind of thing.
Attach the data in a .mat or .txt or .csv file if you need more help.
