PcA和Fisher方法的人脸识别,希望对大家有用，

用于实现支持向量机的核函数，常用的四种，多项式，线性，高斯(Used to implement SVM kernel function, four common)

总结的Matlab常用函数，很有用的终极版笔记，可以打印出来，方便查找和学习。(The functions of Matlab are summarized.This note can be used to find the function you need quickly. )

The Z-source converter overcomes the conceptual and theoretical barriers and limitations of the traditional voltage-source converter (abbreviated as V-source converter) and current-source converter (abbreviated as I-source converter) and provides a novel power conversion concept. The Z-source concept can be applied to all dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion.

灰色预测模型能够通过以往的数据预知未来的数据，准确率高，鲁棒性强(Gray prediction model can predict the future through the past data of data, high accuracy and robustness)

实现伪距单点定位，带测试数据，MATLAB编写，有注释(Realize pseudo-range single point positioning, with test data, written in MATLAB, with notes)

预加重和去加重是语音处理必不可少的环节，得到纯净语音(Pre-emphasis and de-emphasis is essential for speech processing areas, are pure voice)

对于初学者很有帮助，程序我都运算过了，尺度熵，直接可以拿来用(very good)

采用偏最小二乘法，数据包传送源码程序，Relief计算分类权重，感应双馈发电机系统的仿真，用于信号特征提取、信号消噪，包含位置式PID算法、积分分离式PID。

emd是HHT（希尔伯特黄变换）的核心过程，该算法可以很好的处理非线性和非稳定信号数据，将复杂数据信号分解成简单信号的组合，目前已被应用到各个领域。
