IntervalIntersection

IntervalIntersection[interval1,interval2,…]

gives the interval representing all points common to each of the intervali.

Details

  • The interval can be any of:
  • CenteredInterval[…]interval given by center and radius
    Interval[…]interval given by end points

Examples

open all close all

Basic Examples  (2)

Find where intervals overlap:

Wolfram Language code: IntervalIntersection[Interval[{-2, 3}], Interval[{1, 4}]]

Find where center-radius intervals overlap:

Wolfram Language code: IntervalIntersection[CenteredInterval[2 + 3I, 1 + I], CenteredInterval[1 + I, 2 + 2I]]

Scope  (3)

Disjoint intervals:

Wolfram Language code: IntervalIntersection[Interval[{-2, 0}], Interval[{1, 4}]]

Use exact symbolic quantities:

Wolfram Language code: IntervalIntersection[Interval[{-2, Pi}], Interval[{E, 4}]]

Intersect intervals of different types:

Wolfram Language code: IntervalIntersection[Interval[{-2, -1 / 2}, {1 / 2, 2}], CenteredInterval[0, 1 + I]]
