 New = [800,750,740,700,500,300];
radius=50;
for k=1:111
for i=1:length(New)
    for j= (i+1):length(New)
        d(i,j)= sqrt((a(k)-New(:,i)).^2+(b(k)-New(:,j)).^2);  % 'a' and 'b' are two matrices of size 1*111
         if (d(i,j)<=radius)
           New(i) = [];
           New(j) = []; 
         end
    end
end
end

This is a common beginner mistake. If you remove the first element of a four element vector, then it resizes to have three elements. But if your code still thinks the vector has four elements and you try to access the fourth element, then you will get an error. That is basically what you are doing.
