Is there a way to reduce the computation time in this Matlab program?

Is there a way to reduce the computation time in this program that eliminates the columns of a matrix A if for a given column the element of line 4 is equal to the element in row 5:

k=1;
for i=1:4000
   if A(4,i) ~= A(5,i)
      B(:,k)=A(:,i);
      k=k+1;
   end
end
