I want to do the eigen analysis of the matrix below mat := {{0, 1, 0, 0, 0, 0, 0, 0, 0, 0}, {-(1 + K + K1), -0.1, K, 0, 0, 0, 0, 0, K1, 0}, {0, 0, 0, 1, 0, 0, 0, 0, 0, 0}, {K, 0, -(1 + 2 K + K1), -0.1, K, 0, 0, 0, K1, 0}, {0, 0, 0, 0, 0, 1, 0, 0, 0, 0}, {0, 0, K, 0, -(1 + 2 K + K1), -0.1, K, 0, K1, 0}, {0, 0, 0, 0, 0, 0, 0, 1, 0, 0}, {0, 0, 0, 0, K, 0, -(1 + K + K1), -0.1, K1, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 1}, {K1, 0, K1, 0, K1, 0, K1, 0, -(1 + 4 K1), -0.1}}; I kept getting a long solution with some Root [] and #1 I do not know what I am doing wrong Any help, Its very urgent Thanks
