matlab绘制三维等高线图的所有方法

1. 使用contour3函数绘制三维等高线图

[X,Y,Z] = peaks(25);
contour3(X,Y,Z,20);

2. 使用surf和contour函数组合绘制三维等高线图

[X,Y,Z] = peaks(25);
surf(X,Y,Z);
hold on;
contour(X,Y,Z,20);

3. 使用contourf函数绘制三维等高线填充图

[X,Y,Z] = peaks(25);
contourf(X,Y,Z,20);

4. 使用isosurface函数绘制三维等值面

[X,Y,Z] = peaks(25);
V = -5:1:5;
isosurface(X,Y,Z,interp3(X,Y,Z,V,X,Y,Z));

5. 使用slice函数绘制三维等值面切片

[X,Y,Z] = peaks(25);
V = -5:1:5;
slice(X,Y,Z,interp3(X,Y,Z,V,X,Y,Z),[],[],[-5,0,5]);

6. 使用isosurface和patch函数组合绘制三维等值面

[X,Y,Z] = peaks(25);
V = -5:1:5;
p = patch(isosurface(X,Y,Z,interp3(X,Y,Z,V,X,Y,Z)));
set(p,'FaceColor','red','EdgeColor','none');

7. 使用trisurf函数绘制三维等高线图

[X,Y,Z] = peaks(25);
tri = delaunay(X,Y);
trisurf(tri,X,Y,Z);

8. 使用trimesh函数绘制三维等高线边界

[X,Y,Z] = peaks(25);
tri = delaunay(X,Y);
trimesh(tri,X,Y,Z);
