I would like to see some unit tests for this. |
|
I tool a closer look into the tests and there aren't any tests for the Differentiate methods at all. |
|
Maybe we can start now having tests for it? |

Adding a method to IInterpolation is a breaking change since IInterpolation is a public interface that consumers of the library can and do implement.
Might be better to leave it out of the interface but keep the method for the classes for which the method is supported.

It’s been more than 2 years that the latest 5.0 release of the library has been published. I’m not the official maintainer but I wouldn’t have something against releasing a 5.1 version with this change among others (it’s adding a feature, not removing existing ones or changing functionality) |

It isn't a realy "breaking" change if one extend an interface. You can simply implement the method as not implemented. However, it could be make sence to introduce an IDifferentiableInterpolation in order to remove the SupportsDifferentiation property. |
