在 MATLAB Online 中打开

x = logical(randi([0,1], 420, 680 ));    % assumed that x is your extracted data from the text file
x_sorted = sort(x, 2);  % sorted array
x_1_count = sum(x, 2);  % counted number of 1's in each row

在 MATLAB Online 中打开

you can read data from text file as

f= fopen('your_text_file.txt', 'r');
x = textscan(f, repmat('%d', 1, 680), 'CollectOutput', 1, 'Delimiter', ',');
x  = x{1}; 
fclose(f);
