know the number of open unsaved(dirty) simulink files

I'm trying to know the number o unsaved files that I have open in my simulink model. I have several open , and the function (strcmp(get_param(gcs,'Dirty'),'on')), is good but only gives me the current unsaved file, if I have more than 1 it doesn't help.

I'm looking for something that does the same think as this:

function saveall_m_files()

service = com.mathworks.mlservices.MLEditorServices;

% Get a vector of all open editors

editors = service.getEditorApplication.getOpenEditors();

% For each editor, if it is dirty, save it

for k = 0:(editors.size - 1)

editor = editors.get(k);

% disp(editor)

if editor.isDirty()

editor.save();

end

end

end

But for slx files, does enyone have any idea?
