- paddle. mv ( x, vec, name=None )
Performs a matrix-vector product of the matrix x and the vector vec.
x (Tensor) – A tensor with shape \([M, N]\) , The data type of the input Tensor x should be one of float32, float64.
vec (Tensor) – A tensor with shape \([N]\) , The data type of the input Tensor x should be one of float32, float64.
name (str, optional) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name.
The tensor which is producted by x and vec.
- Return type
