I have trouble with meaning of matrix
I wanted to mean adt1~adt12
mean(mmadt) didn't work because of minimum matrix
how can I mean with double type?

mean() does not take the number of items in the second argument - that would be the dimension (direction) along which to take the mean of a matrix. Instead, try summing up and dividing.
theSum = 0;
for k = 1 : nFiles
thisFileName = fullfile(filelist(k).folder, filelist(k).name);
fprintf('Reading %s\n', thisFileName);
theSum = ncread(thisFileName, 'adt')
end
adt12Mean = theSum / nFiles

I just used the name you did, which is not normally what I'd do. I'd do this:
theSum = 0;
for k = 1 : nFiles
thisFileName = fullfile(filelist(k).folder, filelist(k).name);
fprintf('Reading %s\n', thisFileName);
theSum = ncread(thisFileName, 'adt')
end
% Compute the mean over all nFiles that we read in.
adtMean = theSum / nFiles
