Function Reference
— Loadable Function: lambda = eig (a)
— Loadable Function: [v, lambda] = eig (a)

The eigenvalues (and eigenvectors) of a matrix are computed in a several step process which begins with a Hessenberg decomposition, followed by a Schur decomposition, from which the eigenvalues are apparent. The eigenvectors, when desired, are computed by further manipulations of the Schur decomposition.

The eigenvalues returned by eig are not ordered.
