Gradient of f
Web7 years ago So, when you show us the vector field of Nabla (f (x,y)) = , you say that the more red the vector is, the greater is its length. However, I noticed that the most red vectors are those in the center (those that should be less red, because closer to the center, smaller the variables) • ( 56 votes) Upvote Flag Dino Rendulić WebNow to the gradient. Using matrix notation, we can write the gradient as a row vector and the formula for the chain rule becomes: Call the matrix on the right (it's the Jacobian matrix ). Note that this also works the other way around too: And call this other matrix . We can invert the first equation to get .
