numpy.angle(z, deg=0)[source]

Return the angle of the complex argument.

Parameters: z : array_like A complex number or sequence of complex numbers. deg : bool, optional Return angle in degrees if True, radians if False (default).
Returns: angle : ndarray or scalar The counterclockwise angle from the positive real axis on the complex plane, with dtype as numpy.float64.

Examples

np.angle([1.0, 1.0j, 1+1j]) # in radians array([ 0. , 1.57079633, 0.78539816]) np.angle(1+1j, deg=True) # in degrees 45.0
