Incomplete template set
[edit]Why are there {{bra}}, {{ket}} and {{bra-ket}} template, but no {{bra-c}}, {{bra-c-ket}} or {{c-ket}} templates? Those would be useful in the same contexts as the existing ones, e.g., in articles about Quantum mechanics.
Using those, the result of applying a linear operator to a vector could be written {{math|{{bra-C|ψ|C}}}} and {{math|{{c-ket|C|ξ}}}} for ⟨ψ|C⟩ and ⟨C|ξ⟩, and the result of applying a linear operator to two vectors could be written {{math|{{bra-C-ket|ψ|C|ξ}}}} for ⟨ψ|C|ξ⟩. -- Shmuel (Seymour J.)
