numpy.angle() function is used when we want to compute the angle of the complex argument. A complex number is represented by “ x + yi ” where x and y are real number and i= (-1)^1/2. The angle is calculated by the formula tan-1(x/y).
Syntax : numpy.angle(z, deg=0)
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).Return :
angle : The counterclockwise angle from the positive real axis on the complex plane, with dtype as numpy.float64.
Code #1 : Working
# Python program explaining# numpy.angle() function# when we want answer in radian import numpy as geekin_list =[2.0, 1.0j, 1 + 1j] print ("Input list : ", in_list) out_angle = geek.angle(in_list) print ("output angle in radians : ", out_angle) |
Output :
Input list : [2.0, 1j, (1+1j)] output angle in radians : [ 0. 1.57079633 0.78539816]
Code #2 : Working
# Python program explaining# numpy.angle() function# when we want answer in degrees import numpy as geekin_list =[2.0, 1.0j, 1 + 1j] print ("Input list : ", in_list) out_angle = geek.angle(in_list, deg = True) print ("output angle in degrees : ", out_angle) |
Output :
Input list : [2.0, 1j, (1+1j)] output angle in degrees : [ 0. 90. 45.]
