Is permutdims == moddims ?

[NoelAraujo]

Looking at the source code, I could not find a function similar to permutedims.
And at ArrayFire documentation, my best guess for an equivalent function is the moddims method.

Please, can someone implement a permutedims for ArrayFire ?!

Actually is the reorder command.
It is already available, and I was straightforward to define a version of permutdims for AFArray.

Here an working example

using ArrayFire
toLook = zeros(2,2,3)
toLook[:,:,1] .= 1
toLook[:,:,2] .= 2
toLook[:,:,3] .= 3

af_toLook = AFArray(toLook)

my_permutedims(x::AFArray, newDims::Tuple{Integer, Integer,Integer}) = reorder(x, newDims[1]-1,newDims[2]-1,newDims[3]-1,3)

println("----- CPU ------")
permutedims(toLook,(3,2,1)) |> display
permutedims(toLook,(1,3,2)) |> display
println("----- GPU ------")
my_permutedims(af_toLook,(3,1,2)) |> display
my_permutedims(af_toLook,(1,3,2)) |> display

all(permutedims(toLook,(3,2,1)) .≈ my_permutedims(af_toLook,(3,1,2))) |> display
all(permutedims(toLook,(1,3,2)) .≈ my_permutedims(af_toLook,(1,3,2))) |> display
