comment how do I calculate Hessian of this function?
Thanks. That's very helpful. Is there any rule to derive this Hessian without expanding the vector to its elements?

Thanks. Is there any good tutorial on matrix calculus? I'm unfamiliar with basic rules.

But if I want to compute $H^{-1} * g$, where $H$ is the Hessian and $g$ is the gradient, would there be easy way?

Thanks Nick. I see where this is going. But I have another question: is it easy to get inverse of the Hessian?
