Constructor & Destructor Documentation

HypreParVector::HypreParVector	(	int	glob_size,
		int *	col
	)

Creates vector with given global size and partitioning of the columns. Processor P owns columns [col[P],col[P+1])

HypreParVector::HypreParVector	(	int	glob_size,
		double *	_data,
		int *	col
	)

Creates vector with given global size, partitioning of the columns, and data. The data must be allocated and destroyed outside.

HypreParVector::HypreParVector ( const HypreParVector & y )

Creates vector compatible with y.

HypreParVector::HypreParVector ( HYPRE_ParVector y )

Creates vector wrapping y.

HypreParVector::~HypreParVector ( )

Calls hypre's destroy function.

Vector* HypreParVector::GlobalVector ( )

Returns the global vector in each processor.

HypreParVector::operator HYPRE_ParVector ( ) const

Typecasting to hypre's HYPRE_ParVector, a.k.a. void *.

HypreParVector::operator hypre_ParVector * ( ) const

Typecasting to hypre's hypre_ParVector*.

HypreParVector& HypreParVector::operator= ( double d )

Set constant values.

Reimplemented from Vector.

HypreParVector& HypreParVector::operator= ( const HypreParVector & y )

Define '=' for hypre vectors.

void HypreParVector::Print ( const char * fname )

Prints the locally owned rows in parallel.

int HypreParVector::Randomize ( int seed )

Set random values.

Reimplemented from Vector.

void HypreParVector::SetData ( double * _data )

Sets the data of the Vector and the hypre_ParVector to _data. Must be used only for HypreParVectors that do not own the data, e.g. created with the constructor: HypreParVector(int glob_size, double *_data, int *col).

Reimplemented from Vector.

hypre_ParVector* HypreParVector::StealParVector ( ) [inline]

Changes the ownership of the the vector.
