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 optimization. The program has five can modify the input parameters: the number of vertical mesh nely, the number of horizontal mesh nelx, keep the volume fraction of material volfrac, penalty factor penal and filter size rmin. Loading mode and the supporting means fixeddofs matrix F can also be selected separately or combined in different ways.)

详细介绍了有限差分法，以及其matlab实现(Details of the finite difference method, and its implementation matlab)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections.
