如何在python中用matplotlib绘制实变量的复值函数

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(-10, 10, 100)  # 创建一个包含100个点的实数范围

def complex_function(x):
    return np.sin(x) + 1j * np.cos(x)  # 这里以sin(x) + cos(x)i为例

y = complex_function(x)

plt.plot(x, np.real(y), label='Real')  # 绘制实部曲线
plt.plot(x, np.imag(y), label='Imaginary')  # 绘制虚部曲线

plt.legend()  # 添加图例
plt.title('Complex Function')  # 添加标题
plt.xlabel('x')  # 添加x轴标签
plt.ylabel('y')  # 添加y轴标签

plt.show()
