EPSGDGetInitialSize
Returns the initial size of the searching space. 
Synopsis
#include "slepceps.h" 
PetscErrorCode EPSGDGetInitialSize(EPS eps,PetscInt *initialsize)
Not Collective
Input Parameter
|  | eps | - the eigenproblem solver context | 
Output Parameter
|  | initialsize | - number of vectors of the initial searching subspace | 
Notes
If EPSGDGetKrylovStart() is PETSC_FALSE and the user provides vectors with
EPSSetInitialSpace(), 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 EPSGDGetKrylovStart() 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.
