If <A HREF="../EPS/EPSGDGetKrylovStart.html#EPSGDGetKrylovStart">EPSGDGetKrylovStart</A>() is PETSC_FALSE and the user provides vectors with
<A HREF="../EPS/EPSSetInitialSpace.html#EPSSetInitialSpace">EPSSetInitialSpace</A>(), up to initialsize vectors will be used; and if the
provided vectors are not enough, the solver completes the subspace with
random vectors. In the case of <A HREF="../EPS/EPSGDGetKrylovStart.html#EPSGDGetKrylovStart">EPSGDGetKrylovStart</A>() being PETSC_TRUE, the solver
gets the first vector provided by the user or, if not available, a random vector,
and expands the Krylov basis up to initialsize vectors.
