一段小波变换程序，演示了小波变换的具体步骤(Wavelet transform for some procedures, to demonstrate the concrete steps of wavelet transform)

航空飞行力学基本坐标系的转换、大气模型等等！(Aviation mechanics coordinate system conversion, atmospheric models and more!)

增量SVM的实例，用于对手势的在线增量学习，有很详细的源码，并实现了SVM的多分类问题，对于模式识别和学习SVM有很大的帮助(Instance of the incremental SVM for gesture online incremental learning, there is a very detailed source, and to achieve a multi-SVM classification, pattern recognition and learning SVM great help)

说明：  RS_232 通信技术详解(8,25)(Detailed RS232)

说明：  平方根升余弦脉冲实例。两个SQRC滤波器的级联组合就成为一个零ISI的滤波器。此程序用于获得平方根升余弦脉冲。(Square root raised cosine pulse instance. Cascade combination of the two SQRC filters to filter a zero ISI. This procedure used to obtain the square root raised cosine pulse.)

股票指数模拟为几何布朗运动，GBM。 参数有五个： s0，dt（time step），均值，标准差，到期时间T； 利用子函数进行10万条轨道的monte carlo 模拟到期日（3个月）的指数点数，从而估计在买入信号出现后，3个月后的损益情况，主要用来估算VAR (Financial risk analysis on Matlab monte carlo simulation, stock index simulation for geometric Brownian motion, GBM. )
