EPSSetUp
Sets up all the internal data structures necessary for the application of the eigensolver. The operations carried out depend on the solver: factorization of a preconditioning matrix or simply the allocation of necessary space.

int EPSSetUp(EPS eps)
Collective on EPS
Input Parameter
eps -eigenproblem solver context
Notes
This function need not be called explicitly in most cases, since EPSSolve()
calls it. It can be useful when one want to measure the set-up time
separately from the solve time.
This function sets a random initial vector if none has been provided.
