qAny symmetric matrix R can be decomposed in the following way through a diagonalization, or
eigenanalysis:
q
q
qWhere E is the matrix with the eigenvectors ei as its columns, and L is the matrix with the eigenvalues li, along its diagonal and zeros elsewhere.
qThe set of eigenvectors, ei, and associated eigenvalues, li, represent a coordinate transformation into a coordinate space where the matrix R becomes diagonal.
