SVDGetDimensions

Gets the number of singular values to compute and the dimension of the subspace.

#include "slepcsvd.h" 
PetscErrorCode SVDGetDimensions(SVD svd,PetscInt *nsv,PetscInt *ncv,PetscInt *mpd)

Not Collective

svd

- the singular value context

	nsv	- number of singular values to compute
	ncv	- the maximum dimension of the subspace to be used by the solver
	mpd	- the maximum dimension allowed for the projected problem

The user can specify NULL for any parameter that is not needed.
