So far I have written a basic Matlab OFDM program. It runs in Matlab without any errors. But when I use it in the Optisystem Matlab component and run the simulation, I have to force close the program after a few seconds although it doesn’t give any errors or something in the due box. I think the problem is due to the incorrect use of input/output signal formats even though I have tried to make the codes according to the Matlab component tutorial pdf files and videos. My M-file is attached here. The program is really simple and adequate comments so as to make it be understood even more easily have been added. I just want to know why the aforementioned problem occurs. Can anyone help?
