I have a need for a matrix exponential function. I’ve implemented one using the Hipparchus `RealMatrix`

classes and I’d like to contribute it into the project, assuming that I didn’t overlook an existing implementation.

So I have two questions:

- I’ve translated the C++ Eigen implementation, so is that going to be OK from a licensing perspective?
- Where is an appropriate place to put it? I was thinking a static method in the
`MatrixUtils`

class?
