Arrays that are circular in certain dimensions

[putianyi889]

What I would appreciate is a way to construct a matrix that is circular in the first dimension while restricted in the other dimension (i.e. should be able to throw BoundsError)

There are two ways to achieve this:

• To add a size property that hard caps the bounds. This would introduce a dependency related to infinite indexing (e.g. InfiniteArrays). This is more straightforward on the surface but are prone to infinite loops at broadcast-like operations.
• To add a dim property that specifies the circular dimensions. checkbounds needs to be overloaded.

Perhaps this a feature for a higher level package. We have that in our Grid types in Meshes.jl for example. Em qui., 18 de jan. de 2024 09:11, Tianyi Pu ***@***.***> escreveu:

I agree that this should go in a different package that adds bound checks fitting your particular needs.
