Linear Transformation
A linear operation rk is a function
Not to be confused with "linear function"
$f : V \to W$ between two linear spaces $V$ and $W$ which respects addition and scalar multiplication; that is, where:
1. $f(\vec v +_V \vec w) = f(\vec v) +_W f(\vec w)$ 2. $f(c \cdot_V \vec v) = c \cdot_W f(\vec v)$
