Note | Eigenvector and Eigenvalue Review
Basic Method When learning the eigenvalue and eigenvector, we are commonly given an equation at the beginning $$ AX = \lambda X \tag{1} $$ Where A is the matrix X is the eigenvector $\lambda$ is the eigenvalue Take an example Q: Find the eigenvalues and eigenvectors of the matrix $$ A = \begin{bmatrix} 1&1&-2\ -1&2&1\ 0&1&-1 \end{bmatrix} $$ A: To get the answer, firstly apply the equation (1) : $$ AX = \lambda X \tag{1} $$ ...
