I want to pick out some rows (in the vector vv, see below) from an array x. The ndims(x) is determined at run time. So far, I use the approach illustrated below. Is there a better way? x1 = [11 12 13; 21 22 23; 31 32 33] x = cat(x1,x1.+100,dims=3) #my array, happens to be a 3D arra…

Two ways: julia> yv = selectdim(x, 1, vv) 2×3×2 view(::Array{Int64, 3}, [1, 3], :, :) with eltype Int64: [:, :, 1] = 11 12 13 31 32 33 [:, :, 2] = 111 112 113 131 132 133 julia> using EllipsisNotation julia> yv == x[vv, ..] true

Pick rows from array (ndims not known in advance)

Maybe something as simple as adding selectdim(A, 2, 3:4) as another example, below the selectdim(A, 2, 3) it has now?
