SVDGetSingularTriplet

Gets the i-th triplet of the singular value decomposition as computed by SVDSolve(). The solution consists in the singular value and its left and right singular vectors.

Synopsis

#include "slepcsvd.h" 
PetscErrorCode SVDGetSingularTriplet(SVD svd,PetscInt i,PetscReal *sigma,Vec u,Vec v)
Not Collective, but vectors are shared by all processors that share the SVD

Input Parameters

svd - singular value solver context
i - index of the solution

Output Parameters

sigma - singular value
u - left singular vector
v - right singular vector

Note

The index i should be a value between 0 and nconv-1 (see SVDGetConverged()). Both U or V can be PETSC_NULL if singular vectors are not required.
