Class Documentation

template<typename T>
class EvalScalar : public sequant::EvalResult

EvalResult for a constant or a variable value.

Template Parameters:

T – numeric type of the constant value (eg. double, complex<double>, etc.)

Public Types

using id_t = size_t

Public Functions

inline explicit EvalScalar(T v) noexcept
inline T value() const noexcept
inline virtual ERPtr sum(EvalResult const &other, std::array<std::any, 3> const&) const override

Sum other EvalResult object with this object.

Note

In std::array<std::any, 3> is expected to be [l,r,res] where the elements are the annotations for left, right and result respectively.

inline virtual ERPtr prod(EvalResult const &other, std::array<std::any, 3> const &maybe_empty, TA::DeNest DeNestFlag) const override

Perform product binary operation with this object and other.

Note

In std::array<std::any, 3> is expected to be [l,r,res] where the elements are the annotations for left, right and result respectively.

inline virtual ERPtr permute(std::array<std::any, 2> const&) const override

Permute this object according to the annotations in the argument.

Note

In std::array<std::any, 2> is expected to be [pre,post] where the elements are the annotations for the eval result before permutation and after permutation respectively.

inline virtual void add_inplace(EvalResult const &other) override

Add other EvalResult object into this object.

inline virtual ERPtr symmetrize() const override

Particle symmetrize the eval result.

inline virtual ERPtr antisymmetrize(size_t bra_rank) const override

Particle antisymmetrize the eval result.

inline virtual ERPtr mult_by_phase(std::int8_t factor) const override
