Who can help me solving this error?

Dear readers,

First of all, all the codes are in a cloud environment. That means that the codes are not directly on my computer and MATLAB has to go through several maps to reach the codes - changing this did not resolve the issue.

Basically, I continuously get the error 'Undefined function or variable FileName'.

Help would be appreciated!

Update: I have skipped all intermediate files and put everything in one file. Now, again, I get the error when trying to evaluate the likelihood function. No clue what is wrong!

Please post the code and explain, why you assume that "KalmanFilter" and "llik_fun_SV" are existing functions. In which folder are they stored and is it included in the path? Please post the messages as text, because screenshots are rather inconvenient. Thanks.

There is no function called KalmanFilter......you need to provide correct path of the function.
