txtfiles = dir '*.txt' ; % pick txt files in directory
Nfiles = length(txtfiles) ; % total number of files
iwant = zeros(Nfiles,1) ; % initialize the avg array
for i = 1:Nfiles % loop for each file
data = importdata(txtfiles(i).name) ; % load the data
iwant(i) = mean(data(:,3)) ; % get the mean
end
