I am doing my thesis on a new seismic isolator and want to model it in the 8-story benchmark building. All the MATLAB files and Simulink blocks in this benchmark building are readable and editable. However, for the main analysis (S-function) a DLL file is referenced that cannot be opened. Somebody said it might be because it has been done in a very old version of MATLAB .
I would like to see if somebody has information on the issue. Please kindly guide me in what to do in order to be able to edit that file.
Thanks
