matlab绘制三个变量的三维图（三维网状图和三维曲面图）

matlab绘制三个变量的三维图（三维网状图和三维曲面图）surf三维曲面图surf(X Y Z) creates a three-dimensional surface plot. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The function also uses Z for the color data so color is proportional to height.程序运行结果如下：mesh(X Y Z) draws a wireframe mesh with color determined by Z so color is proportional to surface height.mesh三维网状图

这篇介绍两个绘制三维图的命令：

• mesh - 绘制三维网状图
• surf - 绘制三维曲面图

matlab代码如下：

绘制三维图的matlab代码示例

程序运行结果如下：

mesh(X Y Z) draws a wireframe mesh with color determined by Z so color is proportional to surface height.

surf(X Y Z) creates a three-dimensional surface plot. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The function also uses Z for the color data so color is proportional to height.

surf三维曲面图

colorbar是色彩条状图的命令，默认显示在图形的右侧。

colorbar displays a vertical colorbar to the right of the current axes or chart. Colorbars display the current colormap and indicate the mapping of data values into the colormap.
