Hi Naazira Badar and Jojo Mathew
yeah i was actually enquiring about that and jojo if u r asking about interfacing an electrical component with optisystem we have already discussed in various other topics but still i would repeat here that u need to right the matlab code and then add a matlab component in the design and double click on the component to import the m.file u can do that by writing the path of that file in the option asking about path and in run command part u have to mention the name of m.file followed by semicolon. then load matlab and run. this is how we interface matlab rest if u r referring to something else please convey.
Regards
Burhan
