What is the closest thing MATLAB has to namespaces?

by

MATLAB has a notion of packages which can be nested and include both classes and functions.

Just make a directory somewhere on your path with a + as the first character, like +mypkg. Then, if there is a class or function in that directory, it may be referred to as mypkg.mything. You can also import from a package using import mypkg.mysubpkg.*.

The one main gotcha about moving a bunch of functions into a package is that functions and classes do not automatically import the package they live in. This means that if you have a bunch of functions in different m-files that call each other, you may have to spend a while dropping imports in or qualifying function calls. Don’t forget to put imports into subfunctions that call out as well. More info:
