Research direction

Start by reviewing the requested ndarray comparison functions and operators in the issue, along with the existing array APIs that would need to support them. Define the comparison scope and expected behavior, including examples such as geq, allclose, isclose, and equal; done means the selected APIs are implemented with tests covering the documented comparisons.

Description

enhancement

Hi,

I come from a Python background. I have used numpy for array-based computing and recently started working on JAX. They have very easy-to-use array comparison functions ^1^3 to check the relative, partial order etc. I find a lack of these functions/operators here. It would be a great enhancement and would help in testing code without writing a bunch of lines to compare errors or check the relationship between two arrays.

Until now I have been doing things like this,

assert!(distance.iter().all(|&d| d >= -ERR_MARGIN));

With the feature, it should more or less look like this,

assert!(distance.geq(-ERR_MARGIN));
