MATLAB: Minimum value is selected always from last iteration

iterative resultsMATLAB Compiler

part_machine=[1  0  0  1  0  1  1;
0  1  1  1  0  0  1;
1  0  0  1  1  0  0;
1  0  0  0  1  0  1;
1  1  0  0  0  1  0;
0  1  0  0  0  1  1];
demand=[600;550;620;500;590;600];
numIterations=3;
for k=1:numIterations
      rand_cell_assigntomachines=randi([0,1],7,3);
      Part_cell=part_machine*rand_cell_assigntomachines;
      Part_cell(Part_cell>=1)=1;
      no_of_movements=sum(Part_cell,2)-1;
      movement_cost=sum(bsxfun(@times,no_of_movements,demand))
    end
  minval=min(movement_cost)
   the result is 
  movement_cost =
          5110
movement_cost =
          6920
movement_cost =
          6300
minval =
          6300
but in 3 iterations, 6300 is not minimum value.. I checked it and the value which is always picked as min is from the last iteration.. why is this so?

Assign to movement_cost(k) instead of overwriting all of movement_cost
