polyeig calculating few polynomial eigenvalue

The eigs routine calculate only few eigenvalues compared to eig. How can few polynomial eigenvalue be calculated rather than all using polyeig?

Could you share more details about the code you are working with? That will help in diagnosing the issue better.

[Fabre François]

A solution would be to linearize the eigenvalue problem and use eigs.

I'm affraid there is no equivalent of EIGS to POLYEIG (vs EIG).
