Dear Mathgroup members, please excuse the confusion in my first help request regarding Eigenvectors. Sometimes it is better to have a look at a book before sending questions. Now I know that Mathematica obtains eigenvectors by applying the constraint Plus@@(e^2) == 1 for every eigenvector e. Thus getting a eigenvector e with eigenvalue 1 and constraint Plus @@ e == 1 is simply a linear programming problem. Since the rows of the matrix m sum to 1, I can replace any one equation by the constraint Plus @@ e == 1. Again sorry for bothering you with 'private lesson' problems.
