VecCreateMPIWithArray

Creates a parallel vector with a user provided array.

Synopsis

int VecCreateMPIWithArray(MPI_Comm comm,int n,int N,Scalar *array,Vec *vv)
Collective on MPI_Comm

Input Parameters

comm - the MPI communicator to use
n - local vector length (or PETSC_DECIDE to have calculated if N is given)
N - global vector length (or PETSC_DECIDE to have calculated if n is given)
array - the user provided array to store the vector values

Output Parameter

vv -the vector Notes: Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the same type as an existing vector. If use provided array is PETSC_NULL, then VecPlaceArray() can be used at a later atage to SET the array for storing the vector values.

Keywords

vector, create, MPI
