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.

Changed in version 1.16.0: This function works on subclasses of ndarray like ma.array.

Notes

Although the angle of the complex number 0 is undefined, numpy.angle(0) returns the value 0.

Examples

>>> 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
