spkit.agg_angles(thetas, agg='mean')

Aggregating Angles (Directional Arrows) (thetas)

Aggregating Directional Arrows (thetas)

Converting polar coordinates to cartesian aaverging there and converting back to polar

Parameters:

thetas: list/array of theta (angles)

agg: str {‘mean’, ‘median’}, default=’mean’

• method to use averaging, mean or median

Returns:

theta_avg: scalar, aggregated angle value

>>> thetas= np.arctan2(np.random.randn(N)+1, np.random.randn(N)-1)
>>> thetas_avg = sp.agg_angles(thetas, agg='mean')
>>> print(thetas_avg)
