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 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.
