# NEPSetUp

Sets up all the internal data structures necessary for the execution of the nonlinear eigensolver.

## Synopsis

    #include "slepcnep.h"
    PetscErrorCode NEPSetUp(NEP nep)

Collective

## Input Parameter

- nep - the nonlinear eigensolver context

## Notes

This function need not be called explicitly in most cases, since `NEPSolve()` calls it. It can be useful when one wants to measure the set-up time separately from the solve time.
