WebSep 3, 2013 · In there, he talks about calculating gradient of xTAx and he does that using the concept of exterior derivative. The proof goes as follows: y = xTAx. dy = dxTAx + xTAdx = xT(A + AT)dx (using trace property of matrices) dy = (∇y)Tdx and because the rule is true for all dx. ∇y = xT(A + AT) WebGradient Calculator.

The 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.
