this is a simple function for convert into Cartesian to polar coordinates and adding two functions

通信PSK调制fsk调制，按定义编写，及相应的误码率计算，里面用到GUI界面，大家可以从相应的代码中截取自己需要的部分(Communication PSK modulation fsk modulation, by definition, write, and the corresponding bit error rate calculation, which uses GUI interface, you can intercept the part they need the corresponding code)

compress a picture, using kmeans Clustering

支持向量机的改进，孪生支持向量机，效果更好，老外写的，供大家学习(Support vector machine improvement, twin support vector machine, better results, foreigners write for everyone to learn)

基于MATLAB的 SSB调制解调实现.利用MATLAB集成环境下的M文件，编写程序来实现SSB的调制解调，并绘制出解调前后的时域和频域波形及叠加噪声时解调前后的时频波形，根据运行结果和波形来分析该解调过程的正确性及信道对信号传输的影响。(MATLAB-based SSB modulation and demodulation to achieve. Advantage of MATLAB M-files integrated environment, programming to achieve SSB modulation and demodulation, and draw out the time before and after demodulation and frequency demodulation waveform and the superimposed noise before and after the time when frequency waveform, according to analysis of operating results and the waveform of the demodulation process of the correct and the channel on the signal transmission.)

基于DFT的瞬时测频算法，及插值算法，最后由图形表示测频结果。(Based on the Instantaneous Frequency Measurement DFT algorithm, and the interpolation algorithm, and finally by the graphical representation of frequency measurement results.)

各种MATLAB的实用程序。分为图形应用、界面设计、图形处理、数值分析几大部分。(Utility of various MATLAB. Into graphics applications, interface design, graphics, numerical analysis of several parts.)
