permuteddims(a::AbstractArray, perm)

Lazy version of permutedims. Defaults to constructing a Base.PermutedDimsArray but can be customized to output a different type of array.

zero!(x::AbstractArray)

In-place version of Base.zero.

module Concatenate

Alternative implementation for Base.cat through cat(!).

This is mostly a copy of the Base implementation, with the main difference being that the destination is chosen based on all inputs instead of just the first.

Additionally, we have an intermediate representation in terms of a Concatenated object, reminiscent of how Broadcast works.

The various entry points for specializing behavior are:

• Destination selection can be achieved through

  Base.similar(concat::Concatenated{Interface}, ::Type{T}, axes) where {Interface}

• Custom implementations:

  Base.copy(concat::Concatenated{Interface}) # custom implementation of cat Base.copyto!(dest, concat::Concatenated{Interface}) # custom implementation of cat! based on interface Base.copyto!(dest, concat::Concatenated{Nothing}) # custom implementation of cat! based on typeof(dest)

Concatenated{Interface,Dims,Args<:Tuple}

Lazy representation of the concatenation of various Args along Dims, in order to provide hooks to customize the implementation.

Concatenate.cat!(dest, args...; dims)

Concatenate the supplied args along dimensions dims, placing the result into dest.

Concatenate.cat(args...; dims)

Concatenate the supplied args along dimensions dims.

See also [concatenate] and cat!.

concatenate(dims, args...)

Concatenate the supplied args along dimensions dims.
