MATLAB: Assign moving window average if 50 % of the values in the window are within a threshold

Question

Hi,

While doing a moving window average, if the 50 % values in that window are less than a certain threshold, how can one assign NaN to the average over that window.

   mvavg = movmean(temp_ms, [left_window right_window],'omitnan',...
                       'Endpoints', 'discard'); 

How should I check for the threshold over the window ?

Answer 1

threshold=5;%whatever you want your threshold to be
threshold2= ;%window size/2
mvavg = movmean(temp_ms, [left_window right_window],'omitnan',...
                       'Endpoints', 'discard'); 
mvsum = movsum(temp_ms<threshold, [left_window right_window],'omitnan',...
                       'Endpoints', 'discard'); 
mvavg(mvsum<threshold2)=nan;
