  • Split Output. Split the result to get one object per result [[0, 1], [2]] –> [[0], [1], [2]]

  • Wrap Output. Keeps original data shape [Matrix, Matrix, Matrix] –> [[Matrix, Matrix], [Matrix]]

• Some routines offer Output Numpy property to output numpy arrays in stead of regular python lists (making the node faster)
