How do I save multiple variables from the workspace as a .out file?

Basically I need to save a couple specific variables(matrices) from the workspace into a .out file. I've tried the save function but this is what happens ( http://gyazo.com/ff01c99fb76da88b3dab5653d7a8b8f6 ).

How can I make so it is readable? Thanks in advance

X = rand(10);
Y = ones(3);
dlmwrite('data.out', X);
dlmwrite('data.out', Y, '-append')

That does help, although it makes it so the two matrices connect making it look like one big matrix instead of two. Any way I can change that? Thank you

[Thorsten]

Write a newline before you append further matrices

dlmwrite('data.out', X);
fprintf(fopen('data.out', 'a'), '\n'); % write newline to 'data.out'
dlmwrite('data.out', Y, '-append')

What if the file name isn't defined, i.e., it is asked to the user by an input

Thank you!

You can use uiputfile():

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
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)

In Thorsten's code I think you should use an fclose() so the file does not remain open:

fid = fopen('data.out', 'at');
if fid ~= -1
    fprintf(fid, '\n'); % write newline to 'data.out'
    fclose(fid);
end

In this case the input is prior to the saving. How do I fix this problem?

Thank you very much!
