接上篇：Matlab精彩画图示例：绘制图上图
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.
mesh三维网状图
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.
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.
