Constructor & Destructor Documentation

CFieldComparison()

template<int D>

Pscf::Prdc::Cuda::CFieldComparison< D >::CFieldComparison

(

)

Default constructor.

Initializes maxDiff and rmsDiff to zero.

Member Function Documentation

compare() [1/2]

template<int D>

double Pscf::Prdc::Cuda::CFieldComparison< D >::compare	(	CField< D > const &	a,
		CField< D > const &	b )

Compare individual fields.

Array dimensions must agree. An Exception is thrown if the capacities of fields a and b are not equal.

Parameters

a	1st field
b	2nd field

Returns

maximum element-by-element difference (maxDiff)

compare() [2/2]

template<int D>

double Pscf::Prdc::Cuda::CFieldComparison< D >::compare	(	DArray< CField< D > > const &	a,
		DArray< CField< D > > const &	b )

Compare arrays of fields associated with different monomer types.

All array dimensions must agree.

An exception is thrown if the capacities of the enclosing DArrays (the number of monomers) are not equal or if the capacities of any pair of individual fields (number of grid points or basis functions) are not equal.

Parameters

a	1st DArray of fields
b	2nd DArray of fields

Returns

maximum element-by-element difference (maxDiff)

maxDiff()

template<int D>

double Pscf::Prdc::Cuda::CFieldComparison< D >::maxDiff ( ) const

inline

Return the precomputed maximum element-by-element difference.

This function returns the maximum difference between corresponding field array elements found by the most recent comparison.

Definition at line 74 of file cuda/CFieldComparison.h.

rmsDiff()

template<int D>

double Pscf::Prdc::Cuda::CFieldComparison< D >::rmsDiff ( ) const

inline

Return the precomputed root-mean-squared difference.

This function returns the root-mean-squared difference between corresponding elements found by the most recent comparison.
