Hello, all you kind mathematica peoples, I'm working on a 200*200 complex matrix with 5 diagonales, which have a parameter, say, alpha in themselves. And the highest order of alpha is 4 (alpha^4), that stands in every elemente in the center line of the matrix. I want to solve the eigenvalues of this matrix. That means I have a charakteristic polynomial of a very high order, maybe 100. I did use 'NSolve', but I did't get any result after 20 hours. What schould I do? Lot of thanks for any suggest.
