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

All dad jokes are homogeneous

Not quite... you need to clamp the component entries because they go out of bounds...

Ah, it's linear in log space.

I do love a good bit of observational humor about which operators are linear and which are not. For example, people say x↦x+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)

If you want the matrix from The Matrix you have to look at the music.
