Questions tagged [vector]
{vector} is about the typesetting of vector notation, e.g. symbols or row vectors/column vectors. For questions about creating vector graphics in a (La)TeX document, use {diagrams}, or a package specific tag. For questions about including externally created graphics in a document, use {graphics}.
