# Adding scripts/functions to your PATH in MATLAB¶

The PATH variable contains a list of paths (directories on your system). This list of paths will be searched, in order, whenever you call a function or a script by name.

If a file you want to run is not in a directory in your PATH variable, MATLAB will not know where to look for it.

To add a directory to the PATH, use addpath() as follows

addpath('/directory/containing/my/script')


Warning

While scripts can have any name, functions in MATLAB must have the same name as the file in which they are contained.

e.g. for the function my_function() to be available it must be in a file called my_function.m.
