The user should provide in v an array of nconv vectors, where nconv is the value returned by EPSGetConverged().
The first k vectors returned in v span a left invariant subspace associated with the first k computed eigenvalues (note that this is not true if the k-th eigenvalue is complex and matrix A is real; in this case the first k+1 vectors should be used). A left invariant subspace Y of A satisfies y'A in Y for all y in Y (a similar definition applies for generalized eigenproblems).
