Fast and differentiable implementations of matrix exponentials, Krylov exponential matrix-vector multiplications ("expmv"), KIOPS, ExpoKit functions, and more. All your exponential needs in SciML form.
[ ] Any code changes were done in a way that does not break public API → strictly speaking, we break the previously allowed usage of sparse matrices, which however lead to runtime errors
[x] All documentation related to code changes were updated
