Detailed Description

template<size_t Dim>
class intrp::Irregular< Dim >

Interpolates a Variables onto an arbitrary set of points.

Details

If the source_mesh uses Spectral::Basis::FiniteDifference, linear interpolation is done in each dimension; otherwise it uses the barycentric interpolation provided by Spectral::interpolation_matrix in each dimension.

interpolate() [1/6]

template<size_t Dim>

ComplexDataVector intrp::Irregular< Dim >::interpolate

(

const ComplexDataVector &

input

)

const

Interpolate a DataVector or ComplexDataVector onto the target points.

Note

When interpolating multiple tensors, the Variables interface is more efficient. However, this DataVector interface is useful for applications where only some components of a Tensor or Variables need to be interpolated.

interpolate() [2/6]

template<size_t Dim>

DataVector intrp::Irregular< Dim >::interpolate

(

const DataVector &

input

)

const

Interpolate a DataVector or ComplexDataVector onto the target points.

Note

When interpolating multiple tensors, the Variables interface is more efficient. However, this DataVector interface is useful for applications where only some components of a Tensor or Variables need to be interpolated.

interpolate() [3/6]

template<size_t Dim>

template<typename TagsList >

Variables< TagsList > intrp::Irregular< Dim >::interpolate

(

const Variables< TagsList > &

vars

)

const

Performs the interpolation on a Variables with grid points corresponding to the Mesh<Dim> specified in the constructor. The result is a Variables whose internal DataVector goes over the list of target_points that were specified in the constructor.

Note

for the void function, result will be resized to the proper size.

interpolate() [4/6]

template<size_t Dim>

void intrp::Irregular< Dim >::interpolate	(	gsl::not_null< ComplexDataVector * >	result,
		const ComplexDataVector &	input
	)		const

Interpolate a DataVector or ComplexDataVector onto the target points.

Note

When interpolating multiple tensors, the Variables interface is more efficient. However, this DataVector interface is useful for applications where only some components of a Tensor or Variables need to be interpolated.

interpolate() [5/6]

template<size_t Dim>

void intrp::Irregular< Dim >::interpolate	(	gsl::not_null< DataVector * >	result,
		const DataVector &	input
	)		const

Interpolate a DataVector or ComplexDataVector onto the target points.

Note

When interpolating multiple tensors, the Variables interface is more efficient. However, this DataVector interface is useful for applications where only some components of a Tensor or Variables need to be interpolated.

interpolate() [6/6]

template<size_t Dim>

template<typename TagsList >

void intrp::Irregular< Dim >::interpolate	(	gsl::not_null< Variables< TagsList > * >	result,
		const Variables< TagsList > &	vars
	)		const

Performs the interpolation on a Variables with grid points corresponding to the Mesh<Dim> specified in the constructor. The result is a Variables whose internal DataVector goes over the list of target_points that were specified in the constructor.

Note

for the void function, result will be resized to the proper size.
