Ironically, being nonlinear, this transformation isn't representable by a matrix.

I do love a good bit of observational humor about which operators are linear and which are not. For example, people say x鈫+1 is linear, but it maps zero to one! Try doing that with a matrix! I do not have this comedy market cornered though (unlike some category theory niches)
