Actually it’s mostly `solve` that is used a lot, not matrix inversion, since it is not as accurate and has other issues as @ivanpribec pointed out.

That being said, `inv(x)` is useful for just experimenting or testing or debugging, I’ve used it a few times. It should go into `stdlib` into its linear algebra module.
