c++ and matlab 散射电流可视化、球体(c++ and matlabScattering current visualization, sphere )

找椭圆的中心，用得到了很多算法，可以借鉴！(Find the ellipse center, many algorithms have been used, you can learn!)

计算谐波信号的离散分数阶傅立叶变换，并求出使信号频谱聚集的最优阶数！(Calculated harmonic signal Discrete Fractional Fourier Transform, and the signal spectrum obtained optimal order together!)

此程序主要应用霍夫曼编码的主程序也是matlab程序(The main application of this procedure the main program is the Huffman code matlab program)

此为matlab的代码。包括数值o45算法及o23算法(This is the matlab code. Including numerical o45 and o23 algorithm algorithm)

用MATLAB编程出自适应时域均衡在均衡前与均衡后的眼图对比（低通信道和多径信道），还有误差曲线(Programming with MATLAB the adaptive time-domain equalizer in the balance before the balance of the eye diagram after the contrast (low communication channel and multi-path channel), as well as the error curve)

人脸定位和识别的完整MATLAB代码，在国外网站上偶然得到的(face localization and identification of the integrity of MATLAB code, the foreign web sites the chance)

particle swarm optimization

逆变器使用的svpwm脉冲simulink仿真，脉冲和桥臂开关对应顺序已经注明。(Svpwm pulse inverter using simulink simulation, pulse, and bridge arm switches corresponding order has been noted.)

实现PSO对PID参数的优化，可以找到局部最优及全局最优参数。(PSO optimized PID parameters can be found in local optimal and global optimal parameters.)
