Saving workspace from a class

I'm looking to save the workspace from a method of a class. Using just 'save(filename)' it saves only the object. Is there a way to save the entiere workspace from a class?

classdef DataFile
  properties
      filename
  end

    methods
        function self=DataFile(filename) % creator 
            self.filename=filename;
        end

        function save(self) %save the current workspace
            save([self.filename, '.mat']);
        end
    end
end

And so how can we save the overall workspace? any property to define in the save call?

It is saving the entire workspace. You are inside a function, and each function has its own workspace. The only thing in that workspace is what has been passed in, which here you name self.

There may be items in an enclosing workspace, but save() without named variables is defined as working with the current workspace.

What overall workspace is that? Are you referring to the workspace of the routine that invokes the save method?

evalin('caller', sprintf('save(''%s.mat'')', self.filename) )

Thanks! actually you made me discover

evalin('base', sprintf('save(''%s.mat'')', self.filename) )
