right eigenvector corresponding to an eigenvalue 1

How can I find the eigenvector corresponding to the eigenvalue

Answer 1

[Sebastian Castro]

As the documentation for the eig function says:

[V,D] = eig(A) returns diagonal matrix D of eigenvalues and matrix V whose columns are the corresponding right eigenvectors, so that A*V = V*D.

So, if you use the command above, for example

• D(2,2) would give you the 2nd eigenvalue
• V(:,2) would give you the 2nd eigenvector

So how would I get the left eigenvector of the matrix?

Also from the documentation for eig (hint: you should look at it!)

[V,D,W] = eig(A) also returns full matrix W whose columns are the corresponding left eigenvectors, so that W'*A = D*W'.
