Elementwise comparison, with array result

3

Would it make sense to have `a.le(b)` (also `a.leq(b)`, `a.ge(b)`, `a.geq(b)`) return boolean arrays? (where `a, b : PartialOrd` and properly broadcastable).

Document all array creation methods in one place

1

There's some nice docs on array creation in the [ndarray for numpy docs](https://docs.rs/ndarray/latest/ndarray/doc/ndarray_for_numpy_users/index.html#rough-ndarraynumpy-equivalents), but it would be nice if there was a separate section in the main documentation that listed...

LinalgScalar does not have to imply Sub and Div

10

Recall the definition of `LinalgScalar`: https://github.com/rust-ndarray/ndarray/blob/eb82c93f0147df38e061597221ece3627f119a60/src/linalg_traits.rs#L18-L28 However, no algorithm involving `LinalgScalar` requires the scalar to be invertible in the additive group and multiplicative semigroup, in this crate at the very...

This PR adds an `array.reserve(axis, additional)` method for use when appending multiple times to an array. It abstracts over the code in `append` that was calling `OwnedRepr::reserve` in order to...

`BitVec` support for `ndarray`?

1

There is a [`bitvec`](https://crates.io/crates/bitvec) crate which offers space efficient storage for one-dimensional `bool` arrays and vectors. I'm contracted for a project which would benefit from `BitArrayD` analogous to `ArrayD`. Eventually...

mapv_into_any doesn't respect storage type

12

Unlike `mapv_into`, `mapv_into_any` currently always returns a heap-allocated `Array` even if the source is something else - in my case, `ArcArray`. It would be great if, like `mapv_into`, it was...

X^T*B doesn't call BLAS gemm

For matrix $A$, $B$, calculating $A^TB$ should be able to use `gemm` routine, however, it doesn't ```rust let a = Array2::::zeros((10000, 1000)); let b = Array2::::zeros((10000, 1000)); let _ =...

Dot product with dyn arrays

Hi, for some reason this isn't working for me: ```rust let a = array![[1.]].into_dyn(); let b = array![[1.]].into_dyn(); let c = a.dot(&b); ``` I'm getting this error: ``` no method...
