11-6

[x,y] = polybool('union', [0 0 1 1], [0 1 1 0], [], [])

The polybool function returns the first input pair: [0 0 1 1], [0 1 1 0]. Now

consider the 'intersection' operation:

[x,y] = polybool('intersection', [0 0 1 1], [0 1 1 0], [], [])

The polybool function returns [], [].

Compatibility Considerations

In previous releases, if one or both pairs of input vertex arrays were empty, the

polybool function would issue an error.
