Level
medium
Description
The theorem that guarantees the congruent diagonalization of a symmetric real matrix is presented, and this process of diagonalization is described from an operational point of view It is also explained how to use this process to determine if a symmetric real matrix is positive definite, negative definite, positive semidefinite, negative semidefinite, or indefinite. With examples (editable pptx).

Level
medium
Description
The Gram-Schmidt orthogonalization procedure is presented, a procedure used to obtain orthogonal basis of finite dimensional vector subspaces in the context of an euclidean space (real or complex). Theoretical justification of the procedure is given, along with two examples that illustrate how it works in practice (editable pptx).
