M = movmean(A,k) M = movmean(A,[kb kf]) M = movmean(___,dim) M = movmean(___,nanflag) M = movmean(___,Name,Value)

To implement a simple causal moving average filter in MATLAB, use filter()
Ten-point moving average filter
B = 1/10*ones(10,1);
out = filter(B,1,input);
Adjust as needed for a different number of time steps.

I think using filtfilt would work... I'm trying to figure something similar out

windowWidth = 11; % Whatever you want.
kernel = ones(windowWidth,1) / windowWidth;
out = filter(kernel, 1, yourInputSignal);
How can I know this window width?
