[V,e]=eig(A,A+B) ?

if [V,e]=eig(A,A+B) , can V^T*A*V=e and V^T*(A+B)*V=I be true ? V^T - being transpose of V

[John D'Errico]

Not a MATLAB question, ask it on a site about mathematics.

[Samhitha Vadlamani]

Sir, but eig(A,A+B) is a MATLAB syntax

[KSSV]

Why worry? As you have MATLAB in hand, pick two matrices A,B and check it your self.

Answer 1

[Matt J]

If A and B are symmetric and either A or B is a multiple of eye(N), it will be true.
