I need to put a specific data of each file together in order, but I don't know what to use to describe its path. For example, all files have only numbers. I need to put the data in the first row and the sixth column of each file together. Maybe I need to use the for loop, but it is too difficult for me.please write a short piece of code.

hello
try this , it will loop in your folder and load all dat files
I assumed here readmatrix is the right function to read your file format
%% define path
fileDir = pwd; % or your specific path / folder
S = dir(fullfile(fileDir,'*.dat')); % get list of data files in directory
S = natsortfiles(S); % sort file names into natural order (what matlab dir does not well) , see FEX :
%(https://fr.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort)
%% Loop inside folder
for k = 1:length(S) % read data in specified sheet
fileName = S(k).name;
out = readmatrix(fullfile(fileDir, fileName)); % or use a structure (S(k).data ) to store the full data structure
end
