Outer product

1

I found that `ArrayBase` has no equivalent method to `np.outer` of `numpy`. This is quite surprising because outer product is a standard feature and is trivial to implement. For example,...

Improvements using const generics

1

There are a few minor features and improvements we can do with const generics. This meta-issue is mainly about those. Big-ticket items get their own issue. In particular remaking index...

Add multislice_axis! macro

1

The next release of `ndarray` will have a `multislice!` macro for easily taking multiple mutable, disjoint slices simultaneously. (#388) This is great, but there are cases where you want to...

Building a 2D ndarray from rows or columns

18

A couple different times I have wanted to construct a 2D array from an iterator of 1D arrays. Is this something that should be added to ndarray? Roughly, I'm thinking...

Before this PR, running `MIRIFLAGS="-Zmiri-tag-raw-pointers" cargo miri test` caused Miri to report undefined behavior for code using the `WindowsIter`, `ExactChunksIter`, and `ExactChunksIterMut` iterators. This PR fixes the underlying issue. Basically,...

Add rustfmt check to CI

5

`rustfmt` is very convenient when writing PRs, but when it's not enforced by CI, the formatting in the project inevitably diverges from the `rustfmt` style. So, when I run `rustfmt`...

Fix Miri failure with -Zmiri-tag-raw-pointers

Before this PR, running `MIRIFLAGS="-Zmiri-tag-raw-pointers" cargo miri test test_map_axis` caused Miri to report undefined behavior in the `test_map_axis` test. This PR fixes the underlying issue. Basically, Miri doesn't like us...

Add .shrink_to_fit() method for Array

2

Some methods (e.g. `.remove_axis()`, `.into_subview()`, and `.slice_move()`) can cause some of the elements in an owned array to be come inaccessable. It would be useful to have a method that...

Fixed axis length support similiar to `Eigen`

2

In [Eigen](https://eigen.tuxfamily.org/index.php?title=Main_Page), We can write `Matrix` to represent a matrix with fixed 4x4 size. In Rust, I would imaging syntax similar to `ArrayBase`, which has no allocation, const bound check...
