VecCreateComp
Creates a new vector containing several subvectors, each stored separately.
Synopsis
#include "slepcvec.h"
PetscErrorCode VecCreateComp(MPI_Comm comm,PetscInt Nx[],PetscInt n,VecType t,Vec Vparent,Vec *V)
Collective
Input Parameters
| comm | - communicator for the new Vec
|
| Nx | - array of (initial) global sizes of child vectors
|
| n | - number of child vectors
|
| t | - type of the child vectors
|
| Vparent | - (optional) template vector
|
Output Parameter
Notes
This is similar to PETSc's VecNest but customized for SLEPc's needs. In particular,
the number of child vectors can be modified dynamically, with VecCompSetSubVecs().
