ggyyree 10 Posted November 24, 2008 Share Posted November 24, 2008 I have got a quadratic form as following: F(w) = g^T * w + (1/2)* w^T * B * w Here T is the matrix transpose. Someone said the if p is a solution to this quadratic form then p is a solution to an equation of the form: (B + aI) * p = -g Here I is the identity matrix. May I ask why please? Thanks a lot!
