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)

Your x is a 2d array. x [i, j] is the preferred syntax. – hpaulj Sep 4, 2018 at 14:00 Your use of a the word matrix is loose. Is it just a 2d ndarray, or a np.matrix? The difference matters. – hpaulj Sep 4, 2018 at 15:31 1 Note you should use x = np.random.uniform (5., 10., size= (N, M)) – Nils Werner Sep 4, 2018 at 16:01 Add a comment 2 AnswersVector Product. A vector is an object that has both the direction and the magnitude. The length indicates the magnitude of the vectors, whereas the arrow indicates the direction. There are different types of vectors. In general, there are two ways of multiplying vectors. (i) Dot product of vectors (also known as Scalar product)A useful way to think of the cross product <a1, a2, a3> x <b1, b2, b3> is the determinant of the 3 by 3 matrix i j k a1 a2 a3 b1 b2 b3 Note that the coefficient on j is -1 times the determinant of the 2 by 2 matrix a1 a3 b1 b3 So the 2nd value is -[(a1*b3)-(a3*b1)] = (a3*b1)-(a1*b3).

So e − π jn = (e π j) − n = ( − 1) − n. I am assuming j is the imaginary unit, or √− 1. It's best to simply sketch an Argand diagram for this. You will soon see that the value of enπj just oscillates between − 1 and 1 depending on whether n is odd or even hence it is equal to ( − 1)n.i j = k. and cyclically: j k = i, k i = j (and so j i = - k, etc...) 4.
