Eigenvectors of a Symmetric Matrix
		q Any symmetric matrix R can be decomposed in the following way through a diagonalization, or eigenanalysis: q Where 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. q The set of eigenvectors, ei, and associated eigenvalues, li, represent a coordinate transformation into a coordinate space where the matrix R becomes diagonal.
