谱处理的瀑布图显示，超好的(Spectral processing waterfall diagram shows, super good)

经典遗传算法，自然编码格式，用来计算任意N维函数的极值(genetic algorithm )

Here the syms toolbox is used and if you try to print any other values than lambda then MATLAB will print the value in fractions and that is unavoidable. So if you need to know the value in decimal, then use the command vpa() on command window

基于MATLAB的FIR滤波器的设计与仿真(MATLAB-based FIR filter design and simulation)

说明：  快速傅里叶变换和离散线性褶积matlab程序，可以直接调用(Fast Fourier transform and discrete linear convolution matlab program, you can directly call)

Photogrammetry matlab tool.

自己写的实现利用K均值分类图片中的物体。水平有限！欢迎指正。(The realization of the writing my own by K mean classification objects in the picture. Level is limited. Welcome to correct.)

分析传统双向渐进结构优化方法（Bi-directional evolutionary structural optimization，简称BESO）存在不足的基础上，针对性的对数值计算进行了合理的改进。并在此基础上分别对宏观结构、微结构优化、材料/结构一体化等相关问题进行了多尺度、多相复合材料布局及拓扑优化等层次系统地研究(Based on the analysis of the shortcomings of the traditional Bi-directional evolutionary structural optimization (BESO), a reasonable improvement is made for numerical computation. Based on that, multi-level, multi-phase composite material layout and topology optimization are studied systematically.)

This is a very good matlab!You can use it for your home work ,or your bussine work！Thank you very much!good luck!bye
