Detailed Description

A class providing an operator for integrating functions defined on a discrete index range.

Template Parameters

IdxRangeQuadrature	The index range over which the function is integrated.
IdxRangeTotal	The index range of the chunk which can be passed to the operator(). This is the IdxRangeQuadrature combined with any batch dimensions. If there are no batch dimensions then this argument does not need to be provided as by default it is equal to the IdxRangeQuadrature.
MemorySpace	The memory space (cpu/gpu) where the quadrature coefficients are saved.

Constructor & Destructor Documentation

template<class IdxRangeQuadrature , class IdxRangeTotal = IdxRangeQuadrature, class MemorySpace = Kokkos::DefaultExecutionSpace::memory_space>

Quadrature< IdxRangeQuadrature, IdxRangeTotal, MemorySpace >::Quadrature ( QuadConstField coeffs )

inlineexplicit

Create a Quadrature object.

Parameters

coeffs The coefficients of the quadrature.

template<class IdxRangeQuadrature , class IdxRangeTotal = IdxRangeQuadrature, class MemorySpace = Kokkos::DefaultExecutionSpace::memory_space>

template<class ExecutionSpace , class IntegratorFunction >

double Quadrature< IdxRangeQuadrature, IdxRangeTotal, MemorySpace >::operator()	(	ExecutionSpace	exec_space,
		IntegratorFunction	integrated_function
	)		const

inline

An operator for calculating the integral of a function defined on a discrete index range.

Parameters

[in]	exec_space	The space on which the function is executed (CPU/GPU).
[in]	integrated_function	A function taking an index of a position in the index range over which the quadrature is calculated and returning the value of the function to be integrated at that point. It should be noted that a Field fulfils these criteria and can be passed as the function to be integrated. If the exec_space is a GPU the function that is passed must be accessible from GPU.

void Quadrature< IdxRangeQuadrature, IdxRangeTotal, MemorySpace >::operator()	(	ExecutionSpace	exec_space,
		Field< double, BatchIdxRange, MemorySpace > const	result,
		IntegratorFunction	integrated_function
	)		const

inline

An operator for calculating the integral of a function defined on a discrete index range by cycling over batch dimensions.

Parameters

[in]	exec_space	The space on which the function is executed (CPU/GPU).
[out]	result	The result of the quadrature calculation.
[in]	integrated_function	A function taking an index of a position in the index range over which the quadrature is calculated (including the batch index range) and returning the value of the function to be integrated at that point. Please note that a Field fulfills the described criteria. If the exec_space is a GPU the function that is passed must be accessible from GPU.
