how to Calculate SSE for 20 center

I have the function bellow:

function y=ObjSSE(x1)
   global Dim Data
    for i=1:size(x1,1)
     c=reshape(x1(i,:),[Dim size(x1,2)/Dim]);
     d=dist(Data,c);
     d=min(d');
     y(i)=sum(d(:));  
 end

           if i x1 = 3.8846    1.9915
                     2.8583    1.1652

               x2 =  5.0831    0.4157
                     4.1981    1.1693

               x3=   3.9004    1.3658
                     5.1233    0.6420

             ..... till x10 

 how can I  loop and calculate  for x values which are from 1 to 10 and calculate y
 ten times and choose the minimum y

The question is not clear.

What is SSE? Sum of Squared Errors? I see no squaring going on. x1 is passed in, so we know what that is, but what are x2,x3, ... x10? Is that "if i" statement supposed to be part of the function's code? What are the values of "Dim" and "Data"? Where is your code for the dist() function?
