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) WebWhether you represent the gradient as a 2x1 or as a 1x2 matrix (column vector vs. row vector) does not really matter, as they can be transformed to each other by matrix transposition.
