给创新工场求职者的一封信 有兴趣的看一下(Innovative workshops to job seekers interested in a look at a letter)

WiMax Matlab Simulation

对fastica工具箱进行了简化和程序的提取，增加了详细的注释。采用fastica算法的matlab程序，用以进行胎儿心电信号的提取。包含数据和程序，希望有用！！(Fastica toolbox to simplify and procedures of extraction, the detailed notes. Matlab program with fastica algorithms for the extraction of fetal ECG. Contains data and programs seek to help!!)

雷达系统仿真,该雷达具有数字化正交解调、数字脉冲处理、固定目标对消、动目标检测（MTD）、和恒虚警（CFAR）处理等功能(Radar system simulation, the radar has a digital quadrature demodulation, digital pulse processing, fixed target for elimination, moving target detection (MTD), and CFAR (CFAR) processing functions)

三相逆变并网，采用全前馈能有效抑制谐振。(Three-phase inverters connected to grid can effectively suppress resonance by using full feed-forward.)

小波变换的经典程序 可以实现一位离散小波变换(xiaobobianhuandejingdinachengxu)

Jacobi迭代求线性方程组，对初学编程的同学很有帮助的(Jacobi iterative linear equations, students of the beginner program helpful)

（2,1,3）卷积码Viterbi译码的matlab(Viterbi decoding algorithm matlab code)

1. 按照式计算相似性矩阵 2. 排除自身的相似度 3. 按照式计算归一化矩阵 4. 按照式计算归一化拉普拉斯图矩阵L 5. 计算L的特征向量，将前个特征值最大的向量按列放置成一个矩阵，即依次为前个特征值最大的特征向量 6. 归一化X形成矩阵Y 7. 对矩阵Y按每行为一个数据点，进行k-means聚类，第行所属的类就是原来所属的类。(1. similarity matrix based on formula computation 2. rule out your own similarity. 3. normalized matrix based on formula computation 4. normalized formula Laplasse matrix L according to formula. 5. Calculate the eigenvectors of L. Place the vectors with the largest eigenvalues in columns into a matrix, that is, the eigenvectors with the largest eigenvalues in turn. 6. normalized X formation matrix Y 7. K-means clustering is applied to matrix Y according to one data point per behavior. The first row belongs to the original class.)
