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.

Synopsis

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.
