The easiest way to eliminate that is with the Savitzky-Golay filter (sgolayfilt function) since a frequency-selective filter will passd the noise as well as the signal in its passband. Use the bandpass, highpass or lowpass functions for the other filtering, and specify 'ImpulseResponse','iir' for best ...
