n. (Mathematics, Physics) quantity with magnitude and direction (represented by an arrow indicating its direction); (Biology) insect which carries diseases, means of disease transfer; route of a plane

Vector may refer to: In mathematics and physics:An element in a vector space, often represented as a coordinate vectorVector (spatial), an object defined by both magnitude and direction; in contrast to a scalar, an object with magnitude onlyProbability vector, a coordinate vector with nonnegative entries summing to one, representing a discrete probability distributionA one-dimensional, directional matrix: a row vector or column vector

(n.)
Same as Radius vector.
