Template Function Pennylane::Util::isApproxEqual(const Data_t *, const std::size_t, const Data_t *, const std::size_t, typename Data_t::value_type)

Function Documentation

template<class Data_t>
inline bool Pennylane::Util::isApproxEqual(const Data_t *data1, const std::size_t length1, const Data_t *data2, const std::size_t length2, typename Data_t::value_type eps = std::numeric_limits<typename Data_t::value_type>::epsilon() * 100)

Utility function to compare complex statevector data.

Template Parameters

Data_t – Floating point data-type.

Parameters

  • data1 – StateVector data array pointer 1.

  • length1 – StateVector data array pointer 1.

  • data2 – StateVector data array pointer 2.

  • length2 – StateVector data array pointer 1.

  • eps – The absolute tolerance parameter.

Returns

true Data are approximately equal.

Returns

false Data are not approximately equal.
