当x和y表示为一维数组时，如何使用matplotlib创建3d曲面图？

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

x = np.linspace(-5, 5, 100)  # 创建包含100个元素的一维数组，范围为-5到5
y = np.linspace(-5, 5, 100)

X, Y = np.meshgrid(x, y)

def f(x, y):
    return np.sin(np.sqrt(x**2 + y**2))

Z = f(X, Y)

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

ax.plot_surface(X, Y, Z, cmap='viridis')

ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
ax.set_title('3D Surface Plot')

plt.show()
