We find that $$\lambda = 2$$ is a root that occurs twice. Then the following equation would be true. The following is an example using Procedure [proc:findeigenvaluesvectors] for a $$3 \times 3$$ matrix. In other words, $$AX=10X$$. You can verify that the solutions are $$\lambda_1 = 0, \lambda_2 = 2, \lambda_3 = 4$$. We need to show two things. Find its eigenvalues and eigenvectors. Steps to Find Eigenvalues of a Matrix. So lambda is the eigenvalue of A, if and only if, each of these steps are true. Sample problems based on eigenvalue are given below: Example 1: Find the eigenvalues for the following matrix? Diagonalize the matrix A=[4â3â33â2â3â112]by finding a nonsingular matrix S and a diagonal matrix D such that Sâ1AS=D.

Thus $$\lambda$$ is also an eigenvalue of $$B$$. Hence, if $$\lambda_1$$ is an eigenvalue of $$A$$ and $$AX = \lambda_1 X$$, we can label this eigenvector as $$X_1$$. Eigenvalue is a scalar quantity which is associated with a linear transformation belonging to a vector space. The computation of eigenvalues and eigenvectors for a square matrix is known as eigenvalue decomposition. Watch the recordings here on Youtube! (Update 10/15/2017.
