只要检测到反电势过零点就可以得到转子的位置信号，就可以实现无刷直流电机的无位置传感器控制。(As long as the position of the rotor is detected by detecting the zero-crossing of the back-EM potential, the position sensorless control of the brushless DC motor can be realized.)

自己编写的matlab中编辑个人模块的S-函数方法，通过这个模块可以实现输入信号变为原来的10倍(Imagecut.rar matlab edit personal module function method of S- this module can be realized by the input signal into a 10 times )

基于MATLAB的支持向量机工具箱，好用(Support vector machine based on MATLAB toolbox, easy to use)

MATLAB实现最小二乘法拟合，可以实现多维的(MATLAB least squares fitting, can realize muti —dimensions )

这篇文章是盲信号处理，因为是英文文章，所以大家看内容就好了。(Principal component analysis (PCA) is a mainstay of modern data analysis- a black box that is widely used but poorly understood. The goal of this paper is to dispel the magic behind this black box. This tutorial focuses on building a solid intuition for how and why principal component analysis works furthermore, it crystallizes this knowledge by deriving from simple intuitions, the mathematics behind PCA . This tutorial does not shy away from explaining the ideas informally, nor does it shy away from the mathematics. The hope is that by addressing both aspects, readers of all levels will be able to gain a better understanding of PCA as well as the when, the how and the why of applying this technique.)

用dtw方法做的语音识别程序，可以识别简单的单个数字(dtw methods using the voice recognition procedure, a simple recognition of individual figures)

Matlab 画图、线条颜色设置，颜色好看，推荐使用(color map change)

本程序实现了一个基本的基于2psk的误码率仿真程序，比较适合初学通信的人士学习。(This program realize a simulation based on Bpsk modulation, and it is suitable for any beginner of telecommunication)

用matlab实现使用约当消去法实现Ax=b的实验及算法(Use with matlab Jordan elimination method to achieve realization of Ax = b of the experiment and algorithm)

测试样本集对每个模式进行加噪处理，噪声值为±0.1。若网络能对加噪模式进行正确分类，则认为该网络已训练完成。(Test sample set for each pattern plus noise processing, the noise value of ± 0.1. If the network can add noise to the model correctly classified, then that the network has completed the training.)
