eigenvector
(foldoc) | eigenvector
A vector which, when acted on by a particular
linear transformation, produces a scalar multiple of the
original vector. The scalar in question is called the
eigenvalue corresponding to this eigenvector.
It should be noted that "vector" here means "element of a
vector space" which can include many mathematical entities.
Ordinary vectors are elements of a vector space, and
multiplication by a matrix is a linear transformation on
them; smooth functions "are vectors", and many partial
differential operators are linear transformations on the space
of such functions; quantum-mechanical states "are vectors",
and observables are linear transformations on the state
space.
An important theorem says, roughly, that certain linear
transformations have enough eigenvectors that they form a
basis of the whole vector states. This is why {Fourier
analysis} works, and why in quantum mechanics every state is a
superposition of eigenstates of observables.
An eigenvector is a (representative member of a) fixed point
of the map on the projective plane induced by a {linear
map}.

vector font
(foldoc) | outline font
vector font
(Or "vector font") A font defined as a set of lines
and curves as opposed to a bitmap font. An outline font
(e.g. PostScript, TrueType, RISC OS) can be scaled to any
size and otherwise transformed more easily than a bitmap font,
and with more attractive results, though this requires a lot
of numerical processing. The result of transforming a
character in an outline font in a particular way is often
saved as a bitmap in a font cache to avoid repeating the
calculations if that character is to be drawn again.

vector graphics
(foldoc) | vector graphics
(Sometimes called "object-oriented" graphics,
though it's nothing to do with object-oriented programming).
The representation of separate shapes such as lines, polygons
and text, and groups of such objects, as opposed to bitmaps.
The advantage of vector graphics ("drawing") programs over
bitmap ("paint") editors is that multiple overlapping elements
can be manipulated independently without using differenet
layers for each one. It is also easier to render an object at
different sizes and to transform it in other ways without
worrying about image resolution and pixels.

vector processor
(foldoc) | array processor
vector processor
(Or "vector processor") A computer, or extension
to its arithmetic unit, that is capable of performing
simultaneous computations on elements of an array or table
of data in some number of dimensions.
The IBM AltiVec (the "Velocity Engine" used in the {Apple
G4} computers) is a vector processor.
Common uses for array processors include analysis of fluid
dynamics and rotation of 3d objects, as well as data
retrieval, in which elements of a database are scanned
simultaneously. Array processors are very rare now (1998).

vector space
(foldoc) | vector space
An additive group on which some (scalar)
field has an associative multiplicative action which
distributes over the addition of the vector space and respects
the addition of the (scalar) field: for vectors u, v and
scalars h, k; h(u+v) = hu + hv; (h+k)u = hu + ku; (hk)u =
h(ku).
