The most straightforward option is using a filter to remove the noise. This works if the noise has a different spectral content than the signal (e.g. signal is bandlimited, noise is white -> a lowpass filter can be used to reduce the amount of noise).
Functions for digital filter design and application can be found in the signal processing toolbox.
