Hi guys, I have a simple question about how to save data. Let's suppose I have two vectors, x and y; I want to save them as a .txt file having two columns given by x and y. I want also to decide the name of the file (e.g. 'myfile.txt') and the directory of the folder where I save the file (e.g. 'C:\\User\Desktop\MyFolder\') in the code. Thank you!

Try this:
% Get the name of the file that the user wants to save.
startingFolder = userpath
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
fid = fopen(fullFullFileName, 'wt');
if fid ~= -1
for row = 1 : length(x)
fprintf(fid, '%f, %f\n', x(k), y(k));
end
fclose(fid);
end

Try putting the file handle into fprintf:
fprintf(fid, '%f, %f\n', x(row), y(row)); % To file.
fprintf(1, '%f, %f\n', x(row), y(row)); % To command window.
