Grad of function

WebJun 29, 2024 · Autograd's grad function takes in a function, and gives you a function that computes its derivative. Your function must have a scalar-valued output (i.e. a float). This covers the common case when you want to use gradients to optimize something. WebI found the following description of the grad function in the autograd source code: def grad (fun, x) "Returns a function which computes the gradient of `fun` with respect to positional argument number `argnum`. The returned function takes the same arguments as `fun`, but returns the gradient instead. The function `fun`should be scalar-valued.

Web“Gradient, divergence and curl”, commonly called “grad, div and curl”, refer to a very widely used family of differential operators and related notations that we'll get to shortly. We will later see that each has a “physical” significance. But even if they were only shorthand 1, they would be worth using.
