numpy.angle()

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

Return the angle of the complex argument.

Parameters:

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.

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
