#include "petscvec.h" PetscErrorCode VecGetValues(Vec x,PetscInt ni,const PetscInt ix,PetscScalar y)Collective on Vec
|x||- vector to get values from|
|ni||- number of elements to get|
|ix||- indices where to get them from (in global 1d numbering)|
VecGetValues() gets y[i] = x[ix[i]], for i=0,...,ni-1.
VecAssemblyBegin() and VecAssemblyEnd() MUST be called before calling this
VecGetValues() uses 0-based indices in Fortran as well as in C.
