The eigenvectors of a square matrix
A
are all
◻
non-zero vectors
v
such that
Av=\lambda v
for some scalar
\lambda
, called the eigenvalue For example if
A=([5,1,-1],[4,2,-4],[3,-3,1])
then we can directly calculate that
([5,1,-1],[4,2,-4],[3,-3,1])([1],[0],[1])=
◻
9.
([5,1,-1],[4,2,-4],[3,-3,1])([1],[0],[1])=
a So we have demonstrated that
([1],[0],[1])
is an eigenvector with eigenvalue Number Note: the Maple notation for the vector
([1],[2],[3])
is
{
(
:<1,2,3:)
} Similarly we can check that
([0],[1],[1])
is an eigenvector with eigenvalue
([1],[1],[0])
is an eigenvector with eigenvalue
