Vector([1, 2, 3]) * x 是什么意思?如果 x 是数字,就是计算标量积(scalar product),结果是一个新 Vector 实例,各个分量都会乘以x——这也叫元素级乘法(elementwise multiplication)。 >>> v1 = Vector([1, 2, 3]) >>> v1 * 10 Vector([10.0, 20.0, 30.0]) >>> 11 * v1 Vector([11.0, ...

Using np.sum(v1 * v2) first computes the element-wise multiplication between v1 and v2 in a vectorized fashion, and you sum the results to produce a single number. A better way to compute the dot product is to use the at-operator (@), as you see with v1 @ v3. This is because...
