How to declare a function as Static if it is defined as an individual file under the class folder?

In the class definition file we define Static functions as such:

methods(Static)
function SomeFunction()
end
end

However, what if the function is defined as an individual file under the class folder? Can I make some declarations like a .h file in C++ or something like:

methods(Static)
SomeFunction(); %This function is actually defined in the class folder
end

You can do exactly what you're describing. The trick (if there is one) is that you leave the keyword function out in the classdef file. Here's an example

Create a folder @foo

Inside @foo, create a foo.m:

classdef foo
    methods (Static)
        argout = staticmethod1(argin)
        staticmethod2(argin)
    end
end

And a staticmethod1.m:

function argout = staticmethod1(argin)
argout = argin^2;
end

And a staticmethod2.m:

function staticmethod2(argin)
disp("argin=" + argin)
end

Test:

>> foo.staticmethod1(3)

ans =

9

>> foo.staticmethod2("asdf")

argin=asdf
