Necessary conditions for a linear program
Homework Statement Consider the following optimization problem: min f(x) s.t. g(x) ≥ 0 h(x) ≤ 0 q(x) = 0 Let xbar satisfy g(x) = h(x) = q(x) = 0. a)State and prove a set of necessary and sufficient conditions for x to be a local minimum. b)How would the conditions...- sdevoe

Eigen Vector Proofs: Proving Real Symmetric Matrix M is Positive Definite
Homework Statement Let M be a symmetric matrix. The eigenvalues of M are real and further M can be diagonalized using an orthogonal matrix S; that is M can be written as M = S^-1*D*S where D is a diagonal matrix. (a) Prove that the diagonal elements of D are the eigenvalues of M...- sdevoe
