Problem with cplexmilp solver

I am trying to replace intlinprog matlab function with cplexmilp but I don't know what's wrong! here is a simple code and it does not find a feasible answer in cplex, however, intlinprog can solve it.

clc
clear

f = [-1 -2 -3]';
Aeq = [-1 1 1; 1 -3 1];
beq = [20 30]';
lb = [0 0 0]';
ub = [20 90 30]';
A = [0 0 1; 1 0 0];
b = [30 200]';
intcon = [1 2 3];

% matlab solver

%  [x, fval, exitflag] = intlinprog(f, intcon, A, b, Aeq, beq, lb, ub);

% Cplex Solver 

     sostype=[];
     sosind=[] ;
     soswt=[];

     ctype = [];
      for i=1:length(A),

     ctype = [ctype;'I'];
      end
  ctype = ctype'; 

   [x,fval,exitflag,output] = cplexmilp(f,Aeq,beq,A,b,sostype,sosind,soswt,lb,ub,ctype)

Results: cplexstatus: 103 cplexstatusstring: 'integer infeasible' iterations: 0 algorithm: 12 time: 0 message: 'No feasible point was found.'

Can somebody give me a comment about what's wrong in my cplex !

You can contact IBM support for this. They will be able to help you out better.

A,b and Aeq, beq has to be changed. It should be [x,fval,exitflag,output] = cplexmilp(f,A,b,Aeq,beq,sostype,sosind,soswt,lb,ub,ctype)
