-----------------------------------------------------------------
Ok, so then let's add a DiagonalMatrix.inverse() method.
But I would also suggest to add a method with an epsilon to check for a
singular matrix:
* DiagonalMatrix inverse() -> uses default epsilon, e.g. 1e-12
* DiagonalMatrix inverse(double epsilon)
* boolean isSingular(double epsilon)
