Conversion

Conversion from Arrays

pconvert is smart enough to handle 2D and 3D vectors at same time:

julia> using PhysicalParticles
julia> pconvert([1.0, 2.0])PVector2D{Float64}(1.0, 2.0)
julia> pconvert([1.0, 2.0, 3.0])PVector{Float64}(1.0, 2.0, 3.0)
julia> pconvert([1.0, 2.0, 3.0, 4.0])ERROR: [1.0, 2.0, 3.0, 4.0]
       Not supported dimension! Use 2D and 3D vectors
julia> a = pconvert([1.0 3.0;
                     2.0 4.0])2-element StructArray(::Vector{Float64}, ::Vector{Float64}) with eltype PVector2D:
 PVector2D{Float64}(1.0, 2.0)
 PVector2D{Float64}(3.0, 4.0)
julia> pconvert([1.0 4.0;
                 2.0 5.0;
                 3.0 6.0])2-element StructArray(::Vector{Float64}, ::Vector{Float64}, ::Vector{Float64}) with eltype PVector:
 PVector{Float64}(1.0, 2.0, 3.0)
 PVector{Float64}(4.0, 5.0, 6.0)

Assign from Arrays

assign_particles takes in three paremeters: particles, symbol and points. Assignment of :Pos, :Vel and :Acc is enough for simulation tasks:
