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.

参考

arctan2

Computes an element-wise inverse tangent of x1/x2.

absolute

Computes an element-wise absolute value.

Examples

>>> import nlcpy as vp
>>> vp.angle([1.0, 1.0j, 1+1j])               # in radians
array([0.        , 1.57079633, 0.78539816])
>>> vp.angle(1+1j, deg=True)                  # in degrees
array(45.)
