Representing a complex number as a matrix makes it into a 2x2 matrix of reals,
That means more data manipulation for the same complex number.
And matrix inverse is hard to do right. There's a lot of numerical
analysis on the subject,
It turns out that just about any operation that can be elegantly written
using a matrix inverse can better be done by a different algorithm.
It's not efficient to represent complex numbers as 2x2 matrices.
