Two matlab files to demonstrate how to fit an ellipsoid directly to a set of 3D points.

对信号去噪，中间包括软阈值，硬阈值处理，garrot阈值，semidoft阈值处理，效果可以。(Of the signal denoising the middle soft threshold and hard threshold garrot threshold the semidoft threshold treatment effect can.)

一种基于调制域分析的过零检测算法改进，克服了传统过零算法不能应用于某些信号的局限，有MATLAB仿真(Zero-crossing detection algorithm based on improved modulation domain analysis, to overcome the traditional limitations of the zero crossing algorithm can not be applied to certain signals, there are MATLAB simulation)

SIFT ALGORITHM IS BEST OPTION

不错的动画效果的demo，真诚希望对大家有帮助，也希望大家来点人气，谢谢。(A good animation demo, sincerely hope to have the help to everybody, also hope to some popularity, thank you.)

异步电机调速系统，参考模型神经网络控制器的感应电机转速(Induction motor speed control system, neural network reference model of induction motor speed controller)

说明：  MATLAB编写的ode45求解转子系统动力学程序，可用于计算响应和临界转速，程序正常可运行，主程序和函数放在同一个txt文件中。(Ode45 program written in MATLAB for solving rotor system dynamics can be used to calculate response and critical speed. The program can run normally. The main program and function are in the same TXT file.)

说明：  多通道和单通道接收到的北斗信号数据，利用接收到的北斗数据（.dat .txt文件），进行解析，得到初始伪距，平滑伪距，载波相位，并计算其标准差，并画图。(The Beidou signal data received by multi-channel and single channel are analyzed by using the Beidou data (. Dat. TXT file). The initial pseudo range, smooth pseudo range and carrier phase are obtained, and the standard deviation is calculated and plotted.)

用MATLAB实现简易计算器，可以计算加减乘除，三角函数，括号运算等等。(Simple calculator with a MATLAB implementation can be calculated addition, subtraction, trigonometry, brackets, etc. operations.)

这是高阶谱工具箱，这在matlab5.3以后的版本中没有的工具箱，很有用的啊！(This is the high-order spectrum Toolbox, which matlab5.3 future versions without the box very useful ah!)
