Scalar¶

class dolfin.cpp.la.Scalar(*args)¶

Bases: dolfin.cpp.la.GenericTensor

This class represents a real-valued scalar quantity and implements the GenericTensor interface for scalars.

Create zero scalar.

Parameters:	comm (MPI_Comm) –

add_local()¶

Add block of values using local indices.

Parameters:	*double block** (const) – *dolfin::la_index num_rows** (const) – *dolfin::la_index const * rows** (const) –
Return type:	void

add_local_value()¶

Add to local increment (added for testing, remove if we add a better way from python)

Parameters:	value (double) –
Return type:	void

copy()¶

Return copy of scalar.

Return type:	std::shared_ptr< Scalar >

get_scalar_value()¶

Get final value (assumes prior apply , not part of GenericTensor interface)

Return type:	double
