RectGrid.convex_hull

RectGrid.convex_hull(self)

Return the smallest IntervalProd containing this grid.

The convex hull of a set is the union of all line segments between points in the set. For a rectilinear grid, it is the interval product given by the extremal coordinates.

Returns

convex_hullIntervalProd

Interval product defined by the minimum and maximum points of the grid.

Examples

>>> g = RectGrid([-1, 0, 3], [2, 4], [5], [2, 4, 7])
>>> g.convex_hull()
IntervalProd([-1.,  2.,  5.,  2.], [ 3.,  4.,  5.,  7.])
