Symbolic Toolbox Users. In Exercises, enter the matrix from the indicated exercise as a symbolic object, as in A = sym([−8,10; −5,7]). Find the characteristic polynomial with p = poly (A), plot with ezplot (p), set the window and grid with axis ([−4, 4, −10 10]), grid on, factor with factor (p), and find the roots with solve (p). Finally, find the eigenvalues with eig(A) and compare with the roots of the characteristic polynomial.
