You can use conv() (in base MATLAB), or sgolay() (in the Signal Processing Toolbox) or other functions. For example
windowSize = 9; % or whatever - bigger # = more smoothing.
smoothedSignal = conv(yourSignal, ones(1, windowSize)/windowSize, 'same');

smoothedSignal is certainly smoother than what you started with. Why do you say it is not? Can you post your data proving it is not smoother?

Dear Mary, you can use smooth function for this purpose. See the following link for more information: http://www.mathworks.de/de/help/curvefit/smooth.html. I hope it helps. Good luck!
