You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: VBA_setup.m

    the code of the file until where you have to start completion: function VBA_setup()
% VBA_setup()
% Cleanly add the VBA_toolbox to the Matlab path.
% Please prefer this function to addpath() or addpath(genpath()) to ensure
% all subfolders are included with the notable exception of the .git tracker.
