template<class PrecisionT, class ComplexT>
void Pennylane::LightningKokkos::Util::SparseMV_Kokkos(Kokkos::View<ComplexT*> x, Kokkos::View<ComplexT*> y, const std::size_t *row_map, const std::size_t row_map_size, const std::size_t *entries_ptr, const ComplexT *values_ptr, const std::size_t numNNZ)

Sparse matrix vector multiply :math: y=A*x.

Parameters

• x – Input vector

• y – Result vector

• row_map_ptr – row_map array pointer. The j element encodes the number of non-zeros above row j.

• row_map_size – row_map array size.

• entries_ptr – pointer to an array with column indices of the non-zero elements.

• values_ptr – pointer to an array with the non-zero elements.

• numNNZ – number of non-zero elements.
