I am trying create a Dictionary from Arrays of Keys and Values julia> id = [1,2,3,4]; julia> coord = [0 0 0;1 0 0;5 3 0;6 5 1]; and I want something like: Dict(id,coord) i.e. julia> X = Dict(1 => [0,0,0], 2 => [1,0,0], 3 => [5,3,0], 4 => [6,5,1]) …

You need: julia> Dict( id .=> [coord[i,:] for i=1:4] ) Dict{Int64,Array{Int64,1}} with 4 entries: 4 => [6, 5, 1] 2 => [1, 0, 0] 3 => [5, 3, 0] 1 => [0, 0, 0] Also, this is faster: julia> Dict( (id[i] => coord[i,:] for i=1:4) ) Dict{Int64,Array{Int64,1}} with 4 entries: 4 => [6, 5, 1] …
