IntervalProd.dist

IntervalProd.dist(self, point, exponent=2.0)

Return the distance of point to this set.

Parameters

pointarray-like or float

Point whose distance to calculate. Its length must be equal to the set’s dimension. Can be a float in the 1d case.

exponentnon-zero float or float('inf'), optional

Exponent of the norm used in the distance calculation.

Returns

distfloat

Distance to the interior of the IntervalProd. Points strictly inside have distance 0.0, points with NaN have distance float('inf').

Examples

>>> min_pt, max_pt = [-1, 0, 2], [-0.5, 0, 3]
>>> rbox = IntervalProd(min_pt, max_pt)
>>> rbox.dist([-5, 3, 2])
5.0
>>> rbox.dist([-5, 3, 2], exponent=float('inf'))
4.0
