torch_ecg.utils.intervals_union

torch_ecg.utils.intervals_union(interval_list: Sequence[Sequence[Real] | list] | list, join_book_endeds: bool = True) → Sequence[Sequence[Real] | list] | list

Find the union of intervals.

This function is used to find the union (ordered and non-intersecting) of all the intervals in interval_list, which is a list of intervals in the form [a, b], where a, b need not be ordered.

Parameters:

• interval_list (GeneralizedInterval) – The list of intervals to calculate their union

• join_book_endeds (bool, default True) – Whether join the book-ended intervals into one (e.g. [[1, 2],[2, 3]] into [1, 3]) or not.

Returns:

The union of the intervals in interval_list

Return type:

GeneralizedInterval

Examples

>>> intervals_union([[1, 2], [3, 4]])
[[1, 2], [3, 4]]
>>> intervals_union([[1, 2], [2, 3]])
[[1, 3]]
>>> intervals_union([[1, 2], [2, 3]], join_book_endeds=False)
[[1, 2], [2, 3]]
>>> intervals_union([[1, 2.1], [1.6, 4], [3.1, 10.9]])
[[1, 10.9]]
