Codercise H.2.1

Iā€™m not sure where does it wrong.

I solved it! I used np.dot instead of * .

Well done @Mayu! As you realized ā€˜*ā€™ is element-wise multiplication, which is not the right kind of multiplication in this case. We need to use matrix multiplication either by using functions or the ā€˜@ā€™ (at) operator.
