Change `NdProducer::Dim` of `axis_windows()` to `Ix1`

2

See #1304 This breaks the public API because the method `axis_windows()` now returns a new `AxisWindows` struct. And the dimension of the `NdProducer::Dim` will always be `Ix1`. If the old...

Implement numpy's `triu` and `tril` methods

5

Hi, I want to propose an implementation of `numpy.triu` and `numpy.tril` methods ([link here](https://numpy.org/doc/stable/reference/generated/numpy.triu.html)) for arrays that are atleast 2 dimensions. ```python3 import numpy as np np.triu([[1,2,3],[4,5,6],[7,8,9],[10,11,12]], k=0) ``` returns:...

Add Zip::any

Consider marking split_at as #[inline]

11

In recursive domain decomposition (the easiest if not most performant way to parallelize iteration using rayon::iter::split() and optimize for cache locality at all cache levels), split_at can easily become a...
