MATLAB: I’ve got a wrong answer on subtract Matrices

implicit expansionMATLAB and Simulink Student Suitesubtract matrices

I've got a wrong solution when I subtract two matrices with Incompatible Sizes between the row and column.
>> s = [-1 8 5]
s =
      -1     8     5
>> t = [7;0;11]
t =
       7
       0
      11
>> s-t
ans =
      -8     1    -2
      -1     8     5
     -12    -3    -6
it should be the following answer:
??? Error using ==> – Matrix dimensions must agree.
