CL_intervDiff

Description

• Computes the difference of sets of intervals.

  The intervals are gathered in two sets (i1 and i2).

  A real number x belongs to the difference of i1 and i2 if it belongs to an interval from i1, and does not belong to any interval from i2.

  

• Notes:

  - The intervals in each set should have empty intersections (use CL_intervUnion if needed).

  - Sets of intervals may be empty. CL_intervDiff(i1,[]) = i1. CL_intervDiff([],i2) = [].

Parameters

i1:

Set of intervals [start ; end] (2xN1)

i2:

Set of intervals [start ; end] (2xN2)

ires:

Difference of i1 and i2 (i1 minus i2) (2xM)

Examples

i1=[ [ 0;20] , [21; 25]]; i2=[ [2;4] , [5.5;5.7] , [6.6;15] , [19;20.5]]; ires = CL_intervDiff(i1,i2);
