A lot of interesting systems with constant coefficients have been discovered in the last thirty years: in control, in economics, in signal processing, even in mathematics. None of these attractive examples is presently included in introductory texts. At present all examples of matrix systems one finds in such texts are either planar or else they are artificial.

None of these attractive examples were included in this paper either.

(Contempt for applications is one of several somewhat widespread instances of anti-intellectualism among mathematicians.)

What are some examples of what Rota is talking about?

Rota died in 1999, so "the last thirty years" can be construed accordingly, but more recent examples could be included here as well.
