In engineering tasks there is often a need for `diff` function (calculate the n-th discrete difference along the given axis). numpy [contains](https://docs.scipy.org/doc/numpy/reference/generated/numpy.diff.html) the function that works with n-d arrays. I...

I want to make `SliceInfo` for generic `ObsD` dimension. Like if `ObsD == Ix1` then `Array1::Slice_mut( sliceInfo_with_Ix1 )`, if `ObsD == Ix2` then `Array2::Slice_mut( sliceInfo_with_Ix2 )` `slice_mut` argument seems need...

Should the examples inside the `examples` folder be moved to the repo `ndarray-examples`?

It seems that the examples here https://github.com/rust-ndarray/ndarray/tree/master/examples can be moved to https://github.com/rust-ndarray/ndarray-examples, which, in my view, doesn't just have to contain machine learning examples, but could contain even simple examples...
