Do you have the Image Processing Toolbox? If so use imdilate(). It's a sliding maximum filter. It slides a window along, of specified length such as 3 elements, and the output is the highest value inside the window.

Try a moving average filter using the smooth function. I think this function is part of the Curve Fitting Toolbox.
