Hi

Could someone show me how to find the eigenvector of this matrix?

[1,0,0

0,1,0

0,0,1] ?

Thanks in advance.

Any will do. (1,0,0), (0,1,0), (0,0,1) form a basis.

Your matrix is the identity matrix. Its characteristic polynomial is , which has three roots, each equal to 1. This is called a degenerate eigenstructure, where every linear combination of -- in this case -- three eigenvectors will have the same eigenvalue.

Hope this helps. - Apr 22nd 2012, 09:41 AMzziziRe: Eigenvector of 3x3 matrix
