The following matrix types can be express used to build interval matrix that are only affected by some parameters (ie. parametric interval matrices):
- `(A0, A1, p)` --> `A0 + p A1` --
- `(A0, A…

This issue is to discuss speeding Matrix.inv for matrices with different kinds of expressions. Here is an example of why we might want to do that:
```python
In [12]: M = randMatrix(5) + randMatrix(5…
