CL_intervUnion

Description

• Computes the union of sets of intervals.

  The intervals are gathered in different sets (i1, i2,...,ip).

  A real number x belongs to the union of (i1, i2,...,ip) if it belongs to at least one interval in one of the sets.

  

• Notes:

  - Only one set may be given. The result is then the union of the intervals that belong to the set.

  - Intervals of length equal to 0 are discarded. (length = end of interval minus beginning of interval)

  - Sets of intervals may be empty: CL_intervUnion(i1,[]) = CL_intervUnion(i1)

  - Resulting set of intervals are sorted in ascending order (first row)

Parameters

i1:

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

i2:

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

ip:

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

ires:

Union of i1,i2...,iN (2xM)
