Find eigenspace

The dimension of the eigenspace corresponding to an eigenvalue is less than or equal to the multiplicity of that eigenvalue. The techniques used here are practical for $2 \times 2$ and $3 \times 3$ matrices. Eigenvalues and eigenvectors of larger matrices are often found using other techniques, such as iterative methods.

So for instance if c=1 then the first equation is already 0=0 (no work needed) and the second requires that y=0 which tells us that x can be anything whatsoever.

Since the eigenspace is 2-dimensional, one can choose other eigenvectors; for instance, instead of vector u 1 the vector \( {\bf u}_1 = \left[ 0, 1, 3 \right]^{\mathrm T} \) could be used as well. Therefore, we cannot use these eigenvectors to build the chain of generalized eigenvectors. Theorem 2. Each -eigenspace is a subspace of V. Proof. Suppose that xand y are -eigenvectors and cis a scalar. Then T(x+cy) = T(x)+cT(y) = x+c y = (x+cy): Therefore x + cy is also a -eigenvector.
