Currently, depending on the matrix type, there are several different ways to get eigenvalues and eigenvectors and it is hard to remember which function goes with which type.
How about we unify the interface? Proposal: eigenspaces: Return a list of tuples, the first element being an eigenvalue and the second being the associated eigenspace. eigenvalues: Return a list of eigenvalues. eigenvectors(left=True, right=False): Return a list of eigenvalues and an associated matrix (or matrices) containing associated eigenvectors. *should we have the following?* eigenvectors_right, eigenvectors_left: Wrapper calls to eigenvalues which return the eigenvalues and either the left or right eigenvalues. The function here *starts* with eigen so that tab completion is helpful. For comparison, Matlab does this with the eig and eigs functions. Mma has Eigenvalues, Eigenvectors, and Eigensystem (which returns eigenvalues and eigenvectors). Thoughts on keeping the current right_eigenvectors and left_eigenvectors?
