EPSSetUp

Sets up all the internal data structures necessary for the execution of the eigensolver. Then calls STSetUp() for any set-up operations associated to the ST object.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSSetUp(EPS eps)

Collective

Input Parameter

• eps - the linear eigensolver context

Notes

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