dask.array.angle
dask.array.angle¶
- dask.array.angle(x, deg=0)[source]¶
Return the angle of the complex argument.
This docstring was copied from numpy.angle.
Some inconsistencies with the Dask version may exist.
- Parameters
- zarray_like (Not supported in Dask)
A complex number or sequence of complex numbers.
- degbool, optional
Return angle in degrees if True, radians if False (default).
- Returns
- anglendarray or scalar
The counterclockwise angle from the positive real axis on the complex plane in the range
(-pi, pi], with dtype as numpy.float64.
Notes
This function passes the imaginary and real parts of the argument to arctan2 to compute the result; consequently, it follows the convention of arctan2 when the magnitude of the argument is zero. See example.
Examples
>>> import numpy as np >>> np.angle([1.0, 1.0j, 1+1j]) # in radians array([ 0. , 1.57079633, 0.78539816]) # may vary >>> np.angle(1+1j, deg=True) # in degrees 45.0 >>> np.angle([0., -0., complex(0., -0.), complex(-0., -0.)]) # convention array([ 0. , 3.14159265, -0. , -3.14159265])
