    PetscErrorCode EPSEVSLSetPolParameters(EPS eps,PetscInt max_deg,PetscReal thresh)

Logically Collective

### Input Parameters

| eps | - the eigensolver context
| max_deg | - maximum degree allowed for the polynomial
| thresh | - threshold for accepting polynomial

### Options Database Keys

| -eps_evsl_pol_max_deg <d> | - set maximum polynomial degree
| -eps_evsl_pol_thresh <t> | - set the threshold

### Note

PETSC_CURRENT can be used to preserve the current value of any of the arguments, and PETSC_DETERMINE to set them to a default value.
