Spectral Theorem: Min-Max Criterion

This lecture covers the Spectral Theorem, focusing on the Min-Max Criterion for symmetric matrices. The instructor explains the concept of positive definite matrices and their properties, such as orthogonality and diagonalization. The lecture delves into the spectral theorem, discussing the existence of orthogonal matrices and their relation to the diagonal matrix. Additionally, it explores the significance of eigenvalues and eigenvectors in the context of symmetric matrices.
