在Python中返回复数参数的角度(以弧度为单位)
要返回复数参数的角度,请在Python中使用numpy.angle()方法。该方法返回复平面上从正实轴逆时针旋转的角度,范围为(-pi, pi],数据类型为numpy.float64。第一个参数z,一个复数或复数序列。第二个参数deg,如果为True,则返回角度的度数;如果为False(默认),则返回弧度。
步骤
首先,导入所需的库:
import numpy as np
使用array()方法创建一个数组:
arr = np.array([1.0, 1.0j, 1+1j])
显示数组:
print("Array...\n", arr)获取数组的类型:
print("\nOur Array type...\n", arr.dtype)
获取数组的维度:
print("\nOur Array Dimension...\n",arr.ndim)获取数组的形状:
print("\nOur Array Shape...\n",arr.shape)
要在Python Numpy中返回复数参数的角度,请使用numpy.angle()方法。该方法返回复平面上从正实轴逆时针旋转的角度,范围为(-pi, pi],数据类型为numpy.float64:
print("\nResult (radians)...\n", np.angle(arr))示例
import numpy as np
# Create an array using the array() method
arr = np.array([1.0, 1.0j, 1+1j])
# Display the array
print("Array...\n", arr)
# Get the type of the array
print("\nOur Array type...\n", arr.dtype)
# Get the dimensions of the Array
print("\nOur Array Dimension...\n",arr.ndim)
# Get the shape of the Array
print("\nOur Array Shape...\n",arr.shape)
# To return the angle of the complex argument, use the numpy.angle() method in Python Numpy
# The method returns the counterclockwise angle from the positive real axis on the complex plane in the range (-pi, pi], with dtype as numpy.float64.
print("\nResult (radians)...\n", np.angle(arr))输出
Array... [1.+0.j 0.+1.j 1.+1.j] Our Array type... complex128 Our Array Dimension... 1 Our Array Shape... (3,) Result (radians)... [0. 1.57079633 0.78539816]
