Dear readers,
I am trying to evaluate a likelihood function, but I get this unforeseen error (attachment). I still get output, but it is unclear to me what the error means and how I can resolve it.
Thank you for your time and effort.
All the best,

You forgot to attach the excel file. I replaced it with a 100x1 random vector, just to check the rest of the code, and for me it runs without errors.
Two other remarks: clc,clear all,close all is cargo cult programming. At the very least you should replace clear all with clear variables. It is better to separate workspaces by using functions. clear all also removes breakpoints, which are an invaluable tool of debugging.
The second remark is that Matlab has a function for infinity: inf. This didn't introduce errors for me, so if there isn't a technical reason because of your project, you shouldn't need to encode another value for infinity.

Thank you for the tips! Still a lot to learn. I will be home again in a few hours and try to incorporate your suggestions.
