在Python中使用matplotlib实现线性模型的三维曲面绘制

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

# 创建数据
x = np.linspace(-10, 10, 100)  # x轴数据范围
y = np.linspace(-10, 10, 100)  # y轴数据范围
X, Y = np.meshgrid(x, y)  # 创建网格点坐标矩阵
Z = 2*X + 3*Y + 4  # 线性模型的z值

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('Linear Model Surface')

plt.show()
