VecCreate
Creates an empty vector object. The type can then be set with VecSetType().
Synopsis
int VecCreate(MPI_Comm comm,int n,int N,Vec *V)
Collective on MPI_Comm
Input Parameter
comm | - the communicator, should be PETSC_COMM_SELF
|
n | - the local vector length
|
N | - total vector length
|
Output Parameter
V -the vector
Notes
You MUST call eitehr VecSetFromOptions() or VecSetType() after this call before the
vector may be used.
Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the
same type as an existing vector.
Keywords
vector, sequential, create, BLAS
