Most of the system models available in Simulink can be implemented using m-files but there are there are some core differences that people prefer to use Simulink. Here we will list som of the advantages of Simulink over m-file simulation. 1- Simulink is Similar to hardware implementation. 2- Simulink is very easy to read as it is like a block diagram that also works. 3- Simulation is done over time so state of the whole system in each time-slot is available.
