[p,n,e] = fileparts(mfilename('fullpath'));

Start with the documentation. It is one of the major advantages of Matlab over competing platforms. Do you understand what these three functions do? Then it is obvious what these lines do. If you don't, you should start with reading the documentation for each of them.
doc fileparts
doc mfilename
doc addpath
I would also suggest modifying this slightly: this code assumes the file separator is /, which is not always true. It is also good practice to add your custom functions to the bottom of the path, so they don't interfere with built-in functions.
% adds subfolder with functions to PATH
[p,n,e] = fileparts(mfilename('fullpath'));
addpath([p filesep 'functions'],'-end');
addpath([p filesep 'test'],'-end'); % only required for the test setups
Instead of using filesep you could also use fullfile to create the full path.

The first line is a comment.
The second file picks out the full name of the file that contains the executing code (mfilename('fullpath')) and splits it into directory (stored in p), filename (stored in n), and extension (stored in e). It ignores the filename and extension after that.
The code then constructs a directory name by adding the sub-directory name 'functions' to the name of the directory that the code was in, and it adds that functions directory to the path.
The code then constructions a directory name by adding the sub-directory name 'test' to the name of the directory that the code was in, and it adds that test directory to the path.
