spmd problem with undefinded function for input arguments of type 'Composite'.

Hello,

i want to use spmd like this:

 bounds = [-2 2;-2 2]; 
 Problem is a matlab file;
 S is a <2*m double> and m is known;
 thirds,fc,c,con,feas_flags,fcncounter,szes,impcons,calltype, are all vectors;
 lengths is a <2*n double> and n is known;
 varargin = {};

 spmd
   for i = 1:size(S,2)
      [lengths,fc,c,con,feas_flags,szes,fcncounter,success] = ...
          DIRdivide(bounds(:,1),bounds(:,2),Problem,S(1,i),thirds,lengths,...
          fc,c,con,feas_flags,fcncounter,szes,impcons,calltype,varargin{:});
   end
 end
 [minval,fminindex] =  min(fc(1:fcncounter)+con(1:fcncounter));

But there is a error when i want to use fc and fcncounter in the last line:Undefined function 'colon' for input arguments of type 'Composite'. How can i correct it?Thank you for the suggestion!

I think a bit more context is needed for this code snippet. How are bounds and S initialized?
