mindsponge.common.vecs_dot_vecs

mindsponge.common.vecs_dot_vecs(v1, v2)

Dot product of vectors $v_1=(x_1,x_2,x_3)$ and $v_2=(y_1,y_2,y_3)$.

$$res=x_1\ast y_1+x_2\ast y_2+x_3\ast y_3$$

Parameters

• v1 (tuple) – vectors ${\overrightarrow{v}}_1$ , length is 3. Data type is constant or Tensor with same shape.

• v2 (tuple) – vectors ${\overrightarrow{v}}_2$ , length is 3. Data type is constant or Tensor with same shape.

Returns

float or Tensor with the same shape as the Tensor in input, dot product result of two vectors .

Supported Platforms:

Ascend GPU

Examples

>>> import mindsponge
>>> v1 = (1, 2, 3)
>>> v2 = (3, 4, 5)
>>> ans = mindsponge.common.vecs_dot_vecs(v1, v2)
>>> print(ans)
