Protected External Methods

As a coding standard, our lab uses external methods as a way of maintaining our modular code. However, I've found that MATLAB doesn't have a way to make the Access for external methods protected. I've found that I can make external methods private by adding a /private/ folder to the class folder, so I was wondering if there was a 'protected' equivalent.

I'm not sure what you mean by external. Is that the same as static?

[David Kim]

External methods are methods that are contained in their own .m files within the class folder. It was how MATLAB did it before the new OOP was introduced. It's still supported, but we'd like to transition to actual OOP principles, such as "protected" inheritance methods.

Basically, inside the class definition create a methods block with properties Acess = protected. Inside that block add the function footprint.

methods (Access = protected)
  [a,b,c]=protectedmethod(x,y,z);
end

Then create a seperate m file in the root class directory named protectedmethod with the header

function [d,e,f]=protectedmethod(u,v,w)
