Шаблон:Documentation subpage This template creates vectors using arrow notation in HTML, as an alternative to boldface.
Parameters
The template has three parameters:
- Vector symbol: Insert the character, i.e. A, Ω etc. Default is A; to immediately show the template is in use, and prevent the arrow moving and overlapping text to one side.
- Arrow direction: Select one of left, right, or double for the arrows →, ←, or ↔ respectively. The default is right.
- Arrow position: Select one of under or over to place the arrow over or under the character symbolizing the vector. The default is over.
The defaults for 2 and 3 are set to match the LaTeX analogue of \vec: .
