Hi , I have some question
about the properties of symmetric positive defifnte matrices.
If A and B are symmetric positive defifnte matrices , then is A+B also a symetric positive definite matrix É

A matrix is positive definite if for all
So lets write it out
Since both are positive difinite the above sum is positive so we are done.
