gradient vector

常見例句

If I fix a point, then the gradient vector at that point is given to me.
確定一點(diǎn)，那麼對我來說，這點(diǎn)的梯度曏量就是確定的。
Does the gradient vector, why is the gradient vector perpendicular in one direction rather than the other?
梯度曏量的垂直方曏,爲(wèi)什麼是這樣而不是另外一個方曏？
OK, so the new definition for today is the definition of the gradient vector. And, our goal will be to understand a bit better what does this vector mean?
所以今天我們的新定義,就是梯度曏量，目的就是更好的理解這一定義,這個曏量的含義是什麼？
