There are multiple ways you can filter these data. You can use bandpass, high or low pass filters, or any other specific filters: https://www.mathworks.com/help/signal/digital-filtering.html
Or you can use the fft itself to select ffrequencies to keep or delete by yourself: https://www.mathworks.com/help/matlab/fourier-analysis-and-filtering.html
