Is there a transpose function in Elixir?

Question

Hi I look for a transpose function in Elixir. For example I have this kind of array a and after calling a function the result should be b:

Answer 1

Here's a slightly different solution:

def transpose(m) where length(m) <2, do: m
def transpose(m) do
  for i <- 0..length(m)-1 do
    Enum.reduce(m,[], fn x,acc -> acc ++ [Enum.at(x,i)] end)
  end
end

where m is your matrix.
