在Python中返回复数参数的弧度角

要返回复数参数的角度，请在Python中使用numpy.angle()方法。该方法返回复数平面上从正实轴逆时针方向的角度，范围为(-pi, pi]，数据类型为numpy.float64。第一个参数z是复数或一系列复数。第二个参数deg如果为True，则以度为单位返回角度；如果为False（默认值），则以弧度为单位返回角度。

步骤

首先，导入所需的库 –

import numpy as np

使用array()方法创建数组-

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)

获取数组的尺寸 –

print("\nOur Array Dimension...\n",arr.ndim)

获取数组的形状 −

print("\nOur Array Shape...\n",arr.shape)

使用Python Numpy中的numpy.angle()方法返回复数参数的角度。该方法返回复平面上与正实轴的逆时针角度在（-pi，pi]范围内的角度，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]
