filtered_data = (double(YourData(1:end-1)) + double(YourData(2:end))) ./ 2;

The above is simple moving average. There are shorter ways of programming this, such as

filtered_data = conv( YourData, [1 1]/2, 'same')

but the code I gave shows the averaging more clearly.

There are many other ways of removing noise from the signal, but you need to know something about what kind of noise it is before you can effectively remove it from the signal.
