说明：  信号统计分析技术实现信号统计分析技术随机信号的自相关于协方差(Signal statistical analysis techniques for signal statistical analysis of random signals Zixiang covariance)

自己编写的matlab微粒群算法工具箱。微粒群算法（pso）是一种人工智能算法，速度比遗传算法快一些。(I have written matlab PSO toolbox. Particle swarm optimization (pso) is an artificial intelligence algorithm, the speed faster than the genetic algorithm.)

in this mfile i have wrote the principal component analysis algorithm in matlab.

超像素块算法，已经试过绝对好用，sp_demo.m是主程序，用之前需要将c++和matlab建立联系(Super-pixel block algorithm' ve tried absolutely easy to use, sp_demo.m main program before using the c++ and matlab establish contact)

说明：  Matlab数据挖掘分析与实战教程，包括matlab基础知识与机器学习算法，实战部分包含10大具体实例及讲解(Tutorial of Matlab data mining analysis)

这是模式识别中常用的Fisher分类准则的函数，适用于样本类别为两类的情形。返回值是最佳投影方向和投影后的分类阈值。(This is a function of pattern recognition used Fisher classification criteria applicable to the category of the sample for the two types of situation. The return value is the best projection direction and projection classification threshold.)

极限学习机在matlab中elm函数调用示例，以及elm源代码。(Extreme Learning Machine in matlab elm function call examples, and elm source code.)

对雷达射频端实施射频噪声干扰，观测雷达目标回波干扰情况。给出了具体的matlab源码，和效果图。(Radio frequency noise jamming is applied to the radio frequency end of the radar, and radar target echo jamming is observed. The specific matlab source code and the effect diagram are given.)

判断输入的式子是否为合适公式，如果是则输出其真值表(The appropriate formula to determine its truth table)
