Ole Sigmund编写的99行Matlab程序是拓扑优化方面的经典案例。该程序有5个可修改的输入参数：竖直方向网格划分数nely,水平方向网格划分数nelx,保留的材料的体积分数volfrac,惩罚因子penal和滤波器大小rmin。加载方式矩阵F和支承方式fixeddofs也可以分别选取不同的方式或组合。-Ole Sigmund prepared by the 99-line Matlab program is a classic example of topology optimizat

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.

空间曲面图 mesh(x,y,z)其中x,y,z为同阶矩阵，每一组对应元素代表一个网格点。 -FIG curved surface mesh (x, y, z) where x, y, z for the same order matrix, each element represents a group corresponding grid point.

一个等温边界条件下计算墙角内温度场的小程序，用户输入墙角两侧温度，墙体热导率，设定网格尺寸后程序便会自动迭代求解并同时以矩阵和三维图形的形式输出运算结果。(A small program to calculate the temperature field inside the corner under the condition of isothermal boundary is introduced. When users enter the temperature on both side

墙角在对流边界情况下的温度场模拟计算程序。用户输入墙角两侧的流体主流温度，对流换热表面传热系数，设定墙角以及计算网格尺寸后，程序可以通过迭代求解墙体的温度场并以矩阵和三维图像的形式输出。(A simulation program for the temperature field of the wall corner under the convective boundary condition. After entering the mainstream temperature of the
