用“gradient vector”造句大全，gradient vector造句

The gradient vector would be going perpendicular to the level.

If I fix a point, then the gradient vector at that point is given to me.

Now, what's the gradient vector?

And we know how to find a normal vector to the level set, namely the gradient vector is always perpendicular to the level set.

And we have learned how to package partial derivatives into a vector, the gradient vector.

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?

Does the gradient vector, why is the gradient vector perpendicular in one direction rather than the other?
