nlcpy.angle

nlcpy.angle(z, deg=False)

Returns the angle of the complex argument.

Parameters

zarray_like

A complex number or sequence of complex numbers.

degbool, optional

Returns angle in degrees if True, radians if False (default).

Returns

anglendarray

The counterclockwise angle from the positive real axis on the complex plane in the range (-pi, pi], with dtype as nlcpy.float64. If z is a scalar, this function returns the result as a 0-dimention array.
