temporian.EventSet.arctan

arctan() -> EventSetOrNode

Calculates the inverse tangent of an EventSet's features.

Can only be used on floating point features.

Example

>>> a = tp.event_set(
...     timestamps=[1, 2, 3, 4],
...     features={"M": [0, 1.0, -1.0, 5.0]},
... )
>>> a.arctan()
indexes: ...
        timestamps: [1. 2. 3. 4.]
        'M': [ 0.      0.7854 -0.7854  1.3734]
...

Returns:

Type	Description
