Matlab: Importing functions in a class

I have a class file in Matlab.

I created i directory structure using the package specifications.

+MyPkg
|--+F1
|--+F2
|--+F3
|  |--fun.m
|--myc.m

My class is myc and it is inserted in the package MyPkg.

A function fun is saved in subpackage F3 in the main one.

I want to use function fun in my class. How???

You need to refer to fun as MyPkg.F3.fun everywhere. Unfortunately, full packages must be used explicitly everywhere in MATLAB (or, you must use import statements).

The way you are describing using classes is the "old" way of doing it in Matlab. I don't know how it all works when you use the "old" way, but Class files make life way easier. I highly recommend them. This way you can put all of the functions for a class in one file. For example, you could create a file:

myclass.m

classdef myclass
  methods
    function out=add(a,b)
      out=a+b
    end
    function out=subtract(a,b)
      out=a-b
    end
  end
end

If you put myclass.m in the same folder as your m-file. Then you can access the class this way:

a=5;
b=3;
asdf=myclass;
c=asdf.add(a,b)
d=asdf.subtract(a,b)

There is a more extensive example at the following link:

I hope that helps.
