torch_ecg.utils.intervals_intersection¶

torch_ecg.utils.intervals_intersection(interval_list: Sequence[Sequence[Real] | list] | list, drop_degenerate: bool = True) → Sequence[Real] | list[source]¶

Calculate the intersection of all intervals in interval_list.

Parameters:

interval_list (GeneralizedInterval) – The list of intervals to yield intersection.
drop_degenerate (bool, default True) – Whether or not drop the degenerate intervals, i.e. intervals with length 0.

Returns:

The intersection of all intervals in interval_list.

Return type:

Interval

Examples

>>> intervals_intersection([[1, 2], [3, 4]])
[]
>>> intervals_intersection([[1, 2], [2, 3]])
[]
>>> intervals_intersection([[1, 2], [2, 3]], drop_degenerate=False)
[[2, 2]]
>>> intervals_intersection([[1, 2.1], [1.6, 4], [3.1, 10.9]])
[]
>>> intervals_intersection([[1, 2.1], [1.6, 4], [0.7, 1.9]])
[1.6, 1.9]
