I want to write this code below :backhand_index_pointing_down: using vectorisation @. so that i don’t iterate in for loops.

    for b in 1:872
        xs = x[:, b]
        ys = y[:, b]
        zs = z[:, b]

        for i in 1:length(xs), j in 1:length(ys), k in 1:length(zs)
            r, θ, ϕ = xs[i], ys[j], zs[k]
            X = r * sin(θ) * cos(ϕ)
            Y = r * sin(θ) * sin(ϕ)
            Z = r * cos(θ)

            push!(all_xs, X)
            push!(all_ys, Y)
            push!(all_zs, Z)
        end
    end

Is my x, y and z array reshaping code of first starting post wrong? :innocent:
