How to calculate the inner product of two vectors in python?

1>>> A=mat ([[1],[2],[3]]);2>>> B=mat ([[0],[2],[3]]);3>>>a4Matrix ([[1],5[2],6[3]])7>>>b8 Matrix ([[0],9[2],Ten[3]]) One>>> a.t*b AMatrix ([[13]])

The above is calculated for the inner product of two column vectors, noting the construction of the column vectors a=mat ([[1],[2],[3]]);

The following is a calculation of the inner product of two line vectors, and the construction of the line vectors is A=mat ([[three]]);

1 >>> A=mat ([[[+]]); 2 >>> b=mat ([[0,2,3]]); 3 >>> a4 matrix ([[[1, 2, 3]])5 >>> b6 Matrix ([[[0, 2, 3]])7 >>> *b.t8 matrix ([[[]])  9
