Hi All,
I have 3D matrix with dimension (61,57,273) the 273 is daily time. 39 weeks has 273 days.
I want to do a weekly average overtime to get (61,57,39).
result = reshape(data,61,57,39,7);
Data_mean = nanmean(result,4);
I am not sure about the reshaping. Any help would be appreciated to correct or suggest another way to do the average.

I have 3D matrix with dimension (61,57,365) the 365 is daily time. I want to do a monthly average overtime to get (61,57,12). But the number of days each month is different. I would be grateful for your help

result = reshape(data,61,57,7,39);
Data_mean = permute(nanmean(result,3), [1 2 4 3]) %permute gets rid of the singleton dimension that results
