how to add multiple functions in matlab

Question

Hi everyone,

I want to add several functions from a single .m file. Is this possible without actually having to create an individual m file for each function?

Answer 1

For later versions of Matlab that support the classdef keyword, I recommend adding the functions as static methods to a class and then calling them from an instance of that class. It can all be done with one .m file:

classdef roof
  methods (Static)
    function res = f1(...)
        ...
    end
    function res = f2(...)
        ...
    end
  end
end

and you call them by

roof.f1();
roof.f2();

Answer 2

It's possible (at least at 2010a). You have just to finish each function by 'end' statement. Like:

function a
   ...
end
function b
   ...
end

Actually, MatLab supports (at least) 4 types of .m files :

• script
• one function per file (you don't have to end function's body by end statement)
• multiple functions per file (you have to)
• classes (see the answer above)
