MATLAB: Fminsearch, linear programme – reg

fminsearchlinprogMATLABOptimization Toolbox

I wrote the following function 'fun_phi1'; I called this function as follows
 fun=@(y) fun_phi1(y);
>> z=fminsearch(fun,zeros(1,200));
it is showing the message 'optimization terminated' infinitely. the message is not stopping.
please correct the mistake in coding.
 function [ fval ] = fun_phi1(y)
  %UNTITLED Summary of this function goes here

  f1=zeros(1,100);
  f2=zeros(1,100);
  c1=randi([1,20],1,100);
  c2=randi([1,20],1,100);
   f1(1,1:100)=[y(1:100).*c1];
   f2(1,1:100)=[y(101:200).*c2];
  lb=zeros(1,100);
  ub=5*ones(1,100);
  %fun=@(x1,x2)(f1+f2);
  x10=zeros(1,100);
  x11=zeros(1,100);
  % f1=@(y)(c1*y(1:100));
  % f2=@(y)(c2*y(101:200));
  [x1,fval1]=linprog(f1,[],[],[],[],lb,ub);
  [x2,fval2]=linprog(f2,[],[],[],[],lb,ub);
  fval=fval1+fval2;
  end

When you call linprog make sure you pass in an options structure that specifies 'Display', 'none'
