Eigenspace. An eigenspace is a collection of eigenvectors corresponding to eigenvalues. Eigenspace can be extracted after plugging the eigenvalue value in the equation (A-kI) and then normalizing the matrix element. Eigenspace provides all the possible eigenvector corresponding to the eigenvalue. Eigenspaces have practical uses in real life:and eigenvectors. Algorithms are discussed in later lectures. From now own, let A be square (m ×m). Let x 6= 0 ∈ IRm. Then x is an eigenvector of A and λ ∈ IR is its corresponding eigenvalue if Ax = λx. The idea is that the action of A on a subspace S of IRm can act like scalar multiplication. This special subspace S is called an eigenspace.
