scalar,
n. 1. (Vector analysis) a. a quantity with magnitude but not direction, such as speed as opposed to velocity.
b. (as modifier) having magnitude but not direction; for example, 2 is a scalar coefficient of the vector v in the vectorial expression 2v. Compare vector, tensor. 2. (Algebra) an element of the array constituting a matrix, or of the field over which a vector space is defined. 3. an element of the ring over which a commutative group is a module.
