PEP_EXTRACT_NORM#
Eigenvector extraction based on the norm.
Notes#
Given the eigenvector of the linearization, \(y\), the eigenvector of the polynomial eigenproblem \(x\) is obtained from the \(i\)th block for which \(|\phi_i(\lambda)|\) is maximum, where \(\phi_i\) is the \(i\)th element of the polynomial basis. In the case of the monomial basis, it will select the first or last block depending on \(|\lambda|\geq 1\) or \(|\lambda|<1\).
This is the default extraction.
