WebThe gradient of a function w=f(x,y,z) is the vector function: For a function of two variables z=f(x,y), the gradient is the two-dimensional vector . This definition … 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.
