Prob_3_2

There are 200 random lines. This program is used to calculate how many intersection points they have.

说明：  采用正交投影生成子空间算法来进行最大似然估计，程序已经运行出结果。可以放心使用(Orthogonal subspace projection algorithm for generating maximum likelihood estimates, the program has run out of results. Safe to use)

Ant Colony Algorithm for Non Constraint Optimization Problem

Virtual Reality Toolbox

图像修复的一篇比较好的文章，将图像分解为卡通和纹理，对于难修复的纹理部分采用纹理合成方法，修复的效果较好(An article in relatively good image restoration, the image is decomposed into a cartoon and texture, texture for the difficult part of the repair method using texture synthesis, repair is better)

Simulates any 1D nearest-neighbour binary cellular automaton

主成分分析是把多个指标化为少数几个终合指标的一种统计分析方法。本源代码为matlab中源代码，并添加了相应的分析注解(Principal Component Analysis is more than a few indicators as a final indicator of a statistical analysis method. Source code for which the source code Matlab, and add the corresponding analysis notes)

《The finite element method using Matlab》源程序及电子书 用Matlab进行有限元分析("The finite element method using Matlab" source procedures and e-books using Matlab for Finite Element Analysis)

通过matlab编程，实现了快速傅里叶基4的变换(Through matlab programming, achieve a fast Fourier transform base 4)

说明：  通带截止频率 =2 4k rad/s，阻带截止频率 =2 8k rad/s，通带波纹系数 =0.3dB, 阻带波纹系数 =50dB,采样频率fs=20000Hz。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter.)
