Run GenerateNavFilterEquations.m in matlab 2017a,Error！

[BreederBai]

When I ran GenerateNavFilterEquations.m using matlab 2017a, I got an error and I was wondering how I could fix this error(The function or variable 'QuatMult' is not defined) and run the script successfully.

it seems that you are in the default address of Matlab.
change the address to where you copy the entire project. all folders and subfolders must be included in the matlab path.

@rafaelmendy Thank you for your help, the error has been resolved, because of the version problem, there is a library function error at runtime, after a little modification I solved. The link in ardupilot AP_NavEKF2_core.h (https://github.com/priseborough/InertialNav/blob/master/derivations/RotationVectorAttitudeParameterisation/GenerateNavFilterEquations.m) seems to have failed. I have opened this link before, but I am not sure if the content is the same as what I am running now. I remember the contents of this connection and can generate most of the C code for the EKF. I don't know if my memory is wrong.
