Comment (by tscrim):
It seems that the matrix is sufficiently complicated that it just runs up
against the Python function call limit. If I run `simplify_full` on the
matrix first, then it works (and I can even run in again to simplify it
further). So this would be one way to hack around this.
Although we might benefit from having a special case for inverting 2x2
matrices using the explicit form:
{{{
[A B]^-1 = __1__ [ D -B]
[C D] AD-BC [-C A]
}}}
This would give another way around this (it should be faster and in some
ways, more robust) as this code only deals with 2x2 matrices.
