Matlab录音程序，可以供学习参考用，欢迎改进。(Matlab recording program, you can reference for the study, welcomed the improvement.)

单缝衍射的光学仿真模拟，基于MATLAB语言(Single-slit diffraction optics simulation, based on MATLAB language)

说明：  ERA模态识别，该算法可以与自然激励技术合用已识别结构模态参数(Era modal identification, which can be used with natural excitation technology to identify structural modal parameters)

一篇描述anti-cycling理论的文章，希望对大家有所帮助。。(bland s least index rule, an article on anti-cycling theory)

matlab 遗传算法GA，粒子群算法PSO,蚁群算法AS 前段时间上智能计算方法实验课上，自己做的程序。帖到这里，希望有人能改进它们，交流经验这样更有价值。 遗传算法解决最小生成树问题，PURFER编码。 粒子群算法做无约束最优化问题。 蚁群算法解决TSP问题。 如果有宝贵经验希望能交流一下，谢谢，呵呵(matlab genetic algorithm GA, particle swarm optimization PSO, ant colony algorithm for calculation of AS some time ago on the intelligent test classes, make their own procedures. Quote here, hope someone can improve them, and exchange of experience which is more valuable. Genetic algorithm to solve the minimum spanning tree problem, PURFER coding. Particle swarm optimization to do unconstrained optimization problem. Ant colony algorithm to solve the TSP problem. If there is hope to exchange our experience, thank you, He He)

说明：  利用小波变换的图像压缩算法，大家共同探讨，共同学习(Wavelet transform image compression algorithm, we explore, learn together)

永磁同步电机(PMSM)电流转速双闭环PI控制，采用矢量控制（FOC）中的id 0方式，以空间矢量脉宽调制来实现磁链圆跟踪。对负载转矩进行交轴电流前馈以抑制外负载扰动。(Permanent Magnet Synchronous Motor (PMSM) current double closed loop speed PI control, vector control (FOC) of id 0 mode, space vector pulse width modulation to achieve flux circle track. Front axle load torque AC current fed to suppress external load disturbance.)

说明：  用于提取语音每帧的mfcc函数，将数据保存在cell文件中，可以直接使用cell，也可经过变换，提取到表格中使用(The MFCC function used to extract each frame of speech is saved in cell file. Cell can be used directly or transformed to extract the data into tables)
