I have time and accelearion vectors (attached excelsheet column A:time and column B: acceleration) and woud like to calculate the moving rms using the following equation. Please note that N is the number of acceleration data points from t-1 to t+1 s so basically the rms should start from t=1s.
N is the number of acceleration data points from t-1 to t+1 s.

a_rms=flip(sqrt(movsum(flip(a).^2)./(1:length(a))));

a_rms=sqrt(movmean(a.^2,N));
