# PEP_EXTRACT_STRUCTURED

Eigenvector extraction using a linear combination of all the blocks.

## Note

Given the eigenvector of the linearization, \(y\), the eigenvector of the polynomial eigenproblem \(x\) is obtained as a linear combination of all the blocks, such that it minimizes a certain norm.
