Coordinates systems : transformations ( continued )
All these transformations can be mathematically represented
by a 3 x 3 square matrix
where only 6 values a,b,c,d,e,f are different
from 0 or 1 ( since we are in a 2D space ). That is why we can also write
it with a vector notation like [ a b c d e f ] .
Transformations convert coordinates and lengths from the
original system to the new system with a relationship like :
