MATLAB: Finding average of a sensor signal

find average of signal

I have a signal as attached.

I want to find the average of this signal. How could this be done?

I tried findmaxima and mean functions. But I am not sure if I get the correct one.

This should help:

data - your array [42x16384]

EDIT

out = mean(reshape(data,size(data,1),[],8),3);

eg:

data - your array [55x72000]

out = mean(reshape(data,size(data,1),[],3),3);

out = squeeze(mean(reshape(data,size(data,1),3,[]),2)) ;
