Python中怎样计算两个向量的内积??

 1 >>> a=mat([[1],[2],[3]]);
 2 >>> b=mat([[0],[2],[3]]);
 3 >>> a
 4 matrix([[1],
 5         [2],
 6         [3]])
 7 >>> b
 8 matrix([[0],
 9         [2],
10         [3]])
11 >>> a.T*b
12 matrix([[13]])

1 >>> a=mat([[1,2,3]]);
2 >>> b=mat([[0,2,3]]);
3 >>> a
4 matrix([[1, 2, 3]])
5 >>> b
6 matrix([[0, 2, 3]])
7 >>> a*b.T
8 matrix([[13]])
9 >>>
