Symbols, letters, numbers, or even words—whatever serves as a convenient label—can be used as the label inside a ket, with the | making clear that the label indicates a vector in vector space. In other words, the symbol "|A " has a recognizable mathematical meaning as to the kind of variable being represented, while just the "A" by itself ...

Brackets: choose one of: bra (for a bra vector), ket (for a ket vector), bra-ket (for the inner product), or; Symbol 1: if 1 is set to bra or ket: enter the first symbol for the bra or ket, if 1 is set to bra-ket: enter the symbol for the bra part of the inner product; Symbol 2: if 1 is set to bra or ket: this parameter is not needed.
In mathematics and physics, vector notation is a commonly used notation for representing vectors, [1] [2] which may be Euclidean vectors, or more generally, members of a vector space. For denoting a vector, the common typographic convention is lower case, upright boldface type, as in v .
