1. That is correct. 2. That isn’t technically a question. I don’t know why, but you may want to see FAQ #5 <http://www.pserc.cornell.edu/matpower/#pfconvergence> for ideas. 3. MATPOWER does not have any functions that return eigenvalues directly, though I don’t doubt that it has functions to help form some of your matrices of interest.
