说明：  计算测地距离，测地距离是众多距离的一种，在高维流行数据分布空间上，欧式距离不再适用，这时就可用到欧氏距离(Computing geodesic distance, geodesic distance is a large distance, popular in high-dimensional data distribution space, the Euclidean distance is no longer applicable, then you can use the Euclidean distance)

Nonlinear Optimization Applications

一款支持向量机的系列小程序，希望对大家有用吧。。(A series of small support vector machine program, we hope to be useful it. .)

螺旋桨气动性能估算程序，计算拉力，扭矩，功率，精度较高(Propeller aerodynamic performance estimation procedure)

完整的OFDM仿真Matlab程序。从发射机到接收机。(Complete OFDM simulation Matlab. From transmitter to receiver.)

基于matlabd的mie散射程序，可以用于计算光散射的各项参数(Michaelis scattering based on MATLAB)

使用Matlab进行wav文件的基音频率提取，包括自相关法、平均幅度差法和倒谱法等。(Wav files in Matlab to extract the pitch frequency, including the auto-correlation method, average magnitude difference method and the cepstrum method.)

The Support Ve ct or Machi ne So fa r we have used a reference as sumpt ion tha t there exists a linear classifier that has a larg e ge ometric margin, i.e., whose decision b oundar y is we ll separa ted from all the training images (e xamples). Such a larg e margin classifier seems like one we would like to use. C an’t we find it more directly? Yes, we can. The clas sifier is known as the Support Ve ctor M achine or SVM for short.
