scalar patterns on his guitar"
2: of or relating to a directionless magnitude (such as mass or
speed etc.) that is completely specified by its magnitude;
"scalar quantity"

The Collaborative International Dictionary of English v.0.48 (gcide)

Scalar \Sca"lar\, n. (Math.)
In the quaternion analysis, a quantity that has magnitude,
but not direction; -- distinguished from a vector, which has
both magnitude and direction.
[1913 Webster]

The Free On-line Dictionary of Computing (foldoc)

1. A single number, as opposed to a {vector} or
{matrix} of numbers. Thus, for example, "scalar
multiplication" refers to the operation of multiplying one
number (one scalar) by another and is used to contrast this
with "matrix multiplication" etc.

2. In a {parallel processor} or {vector
processor}, the "scalar processor" handles all the sequential
operations - those which cannot be parallelised or vectorised.

See also {superscalar}.

3. Any data type that stores a single value
(e.g. a number or {Boolean}), as opposed to an {aggregate}
data type that has many elements. A {string} is regarded as a
scalar in some languages (e.g. {Perl}) and a vector of
{characters} in others (e.g. {C}).
