for i=0:287
    c = '.dat';
    i=int2str(i);
    str = append(i,c);
    [filename,pathname] = uigetfile(str);
    fileID = fopen(filename, 'r');
    dataArray = textscan(fileID, '%f');
    fclose(fileID);
    radarData = dataArray{1};
    clearvars fileID dataArray ans;
    "data processing part"
end

I have 288 data in .dat format naming like 0.dat, 1.dat, 2.dat,............,287.dat,288.dat. When I run the above code, a popup window appears to select the dataevery time loop runs. How to automate the data selection process?

If you do not want to call uigetfile, remove this command:

pathname = 'C:\Your\Folder';
for i = 0:287
    filename = fullfile(pathname, sprintf('%d.dat', i));
    [fileID, msg] = fopen(filename, 'r');
    assert(fileID > 0, msg);
    
    dataArray = textscan(fileID, '%f');
    fclose(fileID);
    
    radarData = dataArray{1};
    % Omit this, because it has no benefits: clearvars fileID dataArray ans;
    % Most of all clearing "ans" is a waste of time only.
    "data processing part"
end
