parfor loop with strings

I have the following parfor with functions F1-F3:

S = strsplit(['hund kat jensen']);

parfor J=1:length(S)
    if J==1
       F1()
    elseif J==2
       F2()
    else
       F3()
    end
end

This work great. But since my S is pretty huge and doesn't necessarily have the same order for each run I would prefer the following string setup:

parfor J=1:length(S)
    this_J=S{J};    % so I get the string name for each J, - here hund kat jensen

      if strcmp(this_J,'hund')
         F1()
      elseif strcmp(this_J,'kat')
         F2()
      elseif strcmp(this_J,'jensen')
         F3()
      end
  end

For some reason parfor cannot handle this kind of work. Anyone have a suggestion? Thanks in advance...

It works, I forgot to activate the parfor instead of for after some tests. Sorry spam, I closed the question
