Web内积(inner product)一般用在内积空间中,点积(dot product)一般用在欧几里得空间中,数量积(scalar product)通常认为与点积是相等的。 欧几里得空间(Euclidean space)是内积空间(inner product space)的一个特例。在实数域且有限维的内积空间(Inner product space)被称作欧几里得空间(Euclidean space) 。 Web函数 描述; dot_product(vector_a, vector_b) 函数返回两个输入向量,它必须具有相同长度的标量积。 matmul (matrix_a, matrix_b) 它返回两个矩阵的矩阵乘积,它必须是一致的, …
