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. WebThe gradient is computed using second order accurate central differences in the interior points and either first or second order accurate one-sides (forward or backwards) differences at the boundaries. The returned gradient hence has the same shape as the input array. Parameters: farray_like harrison county indiana obits
