Is it possible to set defaults for only a part of a Symbolics.Arr when defining a model? So can I for example only set defaults for pos[:, 4:8], while not setting defaults for pos[:, 1:3] and pos[:, 9:10]?

  @variables begin
        pos(t)[1:3, 1:10] = pos_
  end

Solution: just set the parts of the array you don’t want to have defaults to nothing.
