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)

Definition at line 28 of file cpu/CFieldComparison.tpp.

References Util::Array< Data >::capacity(), and UTIL_CHECK.

◆ 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 field
b	2nd DArray of field

Returns: maximum element-by-element difference (maxDiff)

Definition at line 63 of file cpu/CFieldComparison.tpp.

References UTIL_CHECK.

◆ maxDiff()

template<int D>

double Pscf::Prdc::Cpu::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 cpu/CFieldComparison.h.

◆ rmsDiff()

template<int D>

double Pscf::Prdc::Cpu::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.
