Matlab: select data from many DAT files and put them into one file

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

thank you, if I want the data in the first row and sixth column of each dat file, where should I put (1,6)?

data in the first row = out(1,:)

data in the sixth column = out(:,6)
