sawtooth signal and moving averege filter

Hi all!

I have a signal, noisy sawtooth signal. see (m-file).

I want to smooth and averege this signal with moving averege filter (maybe also kalman filter).

I did it in may program. But i have a problem: In the time where the step happens, i need no values i need just the step (from max to min).

How it could be done in matlab

    % code

t=(1:0.01:10)'; y=sawtooth(t,1); noise = 0.8*rand(901,1); y1 = y+noise; % kal=kalmanf(y1*z) ma=conv(y1,ones(5,1)/5);

plot(y1) hold on stem(ma,'r')

end
