Linear Transformations and Isomorphisms
Vector Transformations:
A 'vector transformation' is a function that is performed on a vector. (i.e. f:V->W)
Examples:
$ \left(\begin{array}{cccc}1&2&3&4\\5&6&7&8\end{array}\right) $
Linear Transformations:
A function L:V->W is a linear transformation of V to W if the following are true:
(1) L(u+v) = L(u) + L(v) (2) L(c*u) = c*L(u)
In other words, a linear transformation is a vector transformation that also meets (1) and (2).
