Measurement Function for Extended Kalman Filter receives -2 input. Why?

=== Simulation (Elapsed: 2 sec) ===
    Error:Error in 'OD/ GPS OD model/Extended Kalman Filter': Failed to evaluate mask initialization commands.
    Caused by:
        Function Measurement expects 1 inputs, or 2 if it has an optional extra input. Instead it receives -2.

Not sure what I am doing wrong here for such an error to occur. Any insights here would be appreciated.

Hi Suraj,

I understand that you are getting the above error when using measurement function for extended kalman filter.

It is difficult to asses the error without the Simulink model.

However from the error message it seems like there is an issue with the arguments which are getting passed to the "measurement" function.

"Measurement function" takes two inputs "sensor" and "filter".

To learn more about the measurement function,please refer to the documentation:

I hope this helps!
