Detailed Description

template<typename BackendTag, typename T>
class pfc::core::SparseVector< BackendTag, T >

Sparse vector for indexed data views.

Represents a sparse view into selected entries of a dense array. Indices are automatically sorted for optimal memory access.

Template Parameters

BackendTag	Backend tag (CpuTag, CudaTag, HipTag)
T	Element type (must be trivially copyable for GPU backends)

Constructor & Destructor Documentation

pfc::core::SparseVector< BackendTag, T >::SparseVector ( size_t size )

inlineexplicit

Construct empty SparseVector.

Parameters

size	Number of entries

pfc::core::SparseVector< BackendTag, T >::SparseVector ( const std::vector< size_t > & indices )

inlineexplicit

Construct SparseVector with given indices.

Parameters

indices Linear indices into dense array (will be sorted)

		const std::vector< T > &	data
	)

inline

Construct SparseVector with indices and initial data.

Parameters

indices	Linear indices (will be sorted)
data	Initial values
