VecCreateSeqWithArray#
Creates a standard,sequential array-style vector, where the user provides the array space to store the vector values.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecCreateSeqWithArray(MPI_Comm comm, PetscInt bs, PetscInt n, const PetscScalar array[], Vec *V)
Collective
Input Parameters#
comm - the communicator, should be
PETSC_COMM_SELFbs - the block size
n - the vector length
array - memory where the vector elements are to be stored.
Output Parameter#
V - the vector
Notes#
Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the
same type as an existing vector.
If the user-provided array is NULL, then VecPlaceArray() can be used
at a later stage to SET the array for storing the vector values.
PETSc does NOT free the array when the vector is destroyed via VecDestroy().
The user should not free the array until the vector is destroyed.
