Finding eigen vector using sym and solve
显示 更早的评论
I am trying to find eigenvectors using the sym and solve functions: However solve only returns answers the all zero vector.
%
G = [6 -1; 2 3];
I = eye(2,2);
xx = sym('xx',[2,1]);
% eigenvalues are 5 and 4
eigvec = solve(G*xx==4*xx);

G = [6 -1; 2 3];
I = eye(2,2);
syms x
eigvec = solve(det(G-x*I)==0)
