no, the algorithm implemented in Eigen is designed efficiently extract all eigenvalues-vectors at once. Nonetheless, this project based on Eigen might be interesting for you:

Is there a way with Eigen to retrieve only the k first eigenvalues and eigenvectors of a nxn self adjoint positive matrix (considering the eigenvalues in decreasing order, and k < n)?
I did not find such a tool in the documentation but maybe I missed something.
