说明：  描绘一种绘制图形的方法，在该程序中使用的是极坐标绘图。会出的图形是花瓣形状。(Describe a method of drawing graphics in the program using polar mapping. Will the graphics is petal shape.)

simple problem(sonar) low pass filter

分析了空间矢量永磁同步电机数学模型 建立了永磁同步电机空间矢量控制系统仿真模型 并在MATLAB环境下对变频调速系统进行仿真实现(the space vector PWM controlled PMSM is analyzed the simulation model of space vector PWM controlled PMSM is presented and speed control system is simulated)

y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level It returns the matrix of all decompositions and the final approximations. Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes. For other wavelets, the filter values alone can be changed or WFILTERS can be used. The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author. Example: clear all t=[0:0.0003:8*pi] x=sin(5000*t)+sin(1000*t) x=x(1:2^16) level=5 Fs=1/0.003 d2wavelet(x,Fs,level) Thanks for Downloading. Don t forget to rate or comment.

Matlab的一个自动图像分割文字识别代码(An automatic image segmentation Matlab code text recognition)

用经典的pca k邻域方法估计点云法向量的程序，带有matlab gui，使用matlab 2016b编译运行成功，输入点云最好为列向量的txt文件，gui中内置了点云显示模块以及生成的点云法向量显示，并且可以输出法向量到txt文件中。(The program of estimating point cloud vector with the classical PCA K neighborhood method, with Matlab GUI, uses MATLAB 2016b to compile and run successfully, the input point cloud is the best column vector TXT file, the point cloud display module and the generated point cloud vector display in GUI are built in Gui, and the normal vector can be output to the txt file.)

The provided code constitues the Fast Feature video Tracking algorithm as implemented in Matlab.

在WINDOWS环境下，使用MATLAB写的PCA代码，移植性好，对于做PCA的能方便使用！(In the WINDOWS environment, the use of PCA written in MATLAB code, portability, and for doing the PCA can easily use!)
