Hi
As I understand, the following code:
mkdir('c:/matlab/myfiles')
addpath('c:/matlab/myfiles')
First creates the folders in question, and in the second line makes it possible to call functions and the like from this folder (and all their subfolders and hence this is why it says the folders are added to the "top" of the search file?)
Unfortunately, I get the following warning (my script is called "test"):
Warning: Name is nonexistent or not a directory: c
> In path at 110
In addpath at 87
In test at 4
Warning: Name is nonexistent or not a directory: /matlab/myfiles
> In path at 110
In addpath at 87
In test at 4
What is that supposed to mean?

Did you intend to attach your test script? It didn't make it.
Incidentally, ADDPATH will not add subfolders. You need GENPATH for that.

so this is already all the script (I justed wanted to understand these functions). So addpath would only work if c would be the very starting point of the path? What then about addpath .... -end? Is this not going for the end of a path?

Try this
addpath(genpath('c:/matlab/myfiles'));
I do it all the time and it works great.

great but what is the difference to using addpath with the "end" suffix?

If you print your path string using the PATH command you will see that addpath appends things to the beginning of the path string by default (without "end"). With the "end" flag, it will append them at the end of the path string.

Generally you only need to worry about it if you're running two versions of MATLAB at the same time, and even then, not always.
