MATLAB: Do Stateflow charts not retain their library links when copied within a library in Stateflow v 4.0 (R12)

Why do Stateflow charts not retain their library links when copied within a library?

I copied my Stateflow chart from one subsystem in my library to another. There was no library link on the new copy. If I do the same thing with a subsystem, the link is created. Why is this different?

This is expected behavior in Stateflow. Library links are not created when a Stateflow chart is copied within a library. This is documented in our release notes found at the folowing link:

http://www.mathworks.com/help/releases/R2011a/toolbox/stateflow/rn/bqntdi4-1.html#bqoa4sz-1

A workaround for this behavior is to include the Stateflow chart in its own subsystem and then copy the subsystem.

This problem has been fixed in Stateflow 5.1.1 (R13SP1). If you are using a previous version, read the following:

This is a bug in Stateflow 4.0 (R12) and later in the way that information in a library chart is passed to its linked charts in existing models. There are no known workarounds.

You need to be very careful about this type of operation. Depending on what do you mean by "parameters", I am not sure if you can merge the changes made both on the library blocks and the instantiated blocks in the model. But if you say that the GUI operation via Link OPtions -> Restore Link can achieve what you want, then you can do it in script. Try an example first to make sure it works before you apply to the whole model.

LibraryBlocks=find_system(MyModel,'FollowLinks','On','LookUnderMasks','All',...
    'LinkStatus','inactive');
% restore libraries, from inside to outside because library might be
% nested
for i=length(LibraryBlocks):-1:1
    try
        Lib_Model=get_param(LibraryBlocks{i},'AncestorBlock');
        Lib_Model=regexprep(Lib_Model,'/.+','');
        open_system(Lib_Model);
        set_param(LibraryBlocks{i},'LinkStatus','restore');
        fprintf(1, 'Info: Restore block ''%s'' from library file "%s".\n\n',LibraryBlocks{i},Lib_Model);                        
    catch %#ok<*CTCH>
        fprintf(2, 'ERROR: Can not restore block ''%s'' to library file "%s".\n\n',LibraryBlocks{i},Lib_Model);                                
    end
end
