WebThe Spectral Theorem. Theorem. (Schur) If A is an matrix, then there is a unitary matrix U such that is upper triangular. (Recall that a matrix is upper triangular if the entries below the main diagonal are 0.). Proof. Use induction on n, the size of A. If A is , it's already upper triangular, so there's nothing to do.. Take , and assume the result is true for matrices. WebFirst, when you project a vector v onto a vector w, the result is a scaled version of the vector w, NOT the vector v: proj (v) = k w, where "k" is a constant and: k = (v ⋅ w/‖w‖²) The formula you first mention [" (v dot w / v …
