EPSGetInvariantSubspace

Gets a basis of the computed invariant subspace.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSGetInvariantSubspace(EPS eps, Vec *v)
Not Collective

Input Parameter

eps -the eigensolver context

Output Parameter

v -an array of vectors

Notes

This function should be called after EPSSolve() has finished.

The user should provide in v an array of nconv vectors, where nconv is the value returned by EPSGetConverged().

The vectors returned in v span an invariant subspace associated with the (nconv) computed eigenvalues. An invariant subspace X of A satisfies Ax in X for all x in X (a similar definition applies for generalized eigenproblems).
