what are the inputs of extended Kalman filter?

Could I connect my states in simulink dirrectly to the extended Kalman filter? or I need to write function in m file?

I don't understand the question. States is normally internal to your system. You need to specify your system with states, but normally those are not the input. Could you clarify your question?

thanks for your respond

my problem is: I have simulated my system( high dimention and coupled nonlinear with 22 states) in simulink with blocks and fcn and I want to use this simulink in part of extended kalman filter that need to define (myStateTransitionFcn) cause writing codes and function in m file for this system is complicated ,atleast I dont know how could I write a comprehensive function without using simulink blocks for this system.

I hope I explained my problem clearly.

Sincerely
