◆ dot() [1/2]

Operator syten::BTT::dot ( Operator const &  a,
Operator const &  b,
Sector const &  sec 
)

Scalar product of two operators, e.g. \( G \cdot F \) is dot(f, g, vacuum), \( G \) will be taken to lie in the dual space in the process.

The result is mapped onto the specified quantum number sector sec. See also MPS::dot() for more details.
