Giá trị riêng của ma trận

Cho A là ma trận bình phương, η là vecto và λ là một đại lượng vô hướng thỏa mãn Aη=λη,
thì λ được gọi là giá trị riêng được liên kết với vecto riêng η của A

Các giá trị riêng của A là gốc của phương trình đặc trưng det (A−λ I) = 0

det((

)−λ(

)): −λ³−λ²+12λ

Giải −λ³−λ²+12λ=0: λ=0, λ=3, λ=−4

Các giá trị riêng là:

λ=0, λ=3, λ=−4
