这是我们参加深圳杯2012年D题的打孔机生产效率的问题，希望对大家有帮助。这可是很强的东西。(This is our participation in Shenzhen Cup 2012 theme punch D productivity problem, we want to help. This is strong stuff.)

巴特沃斯低通滤波器，实现滤波。效果很好！(a butterworth filter )

一份学习Matlab混合编程的资料，很值得初学者看一下(Study mix program of MATLAB)

说明：  利用matlab仿真实现载波的平方环载波同步,costas环载波同步和符号同步(The square loop carrier synchronization, Costas loop carrier synchronization and symbol synchronization are realized by MATLAB simulation)

说明：  准椭圆函数交叉耦合滤波器耦合系数的提取程序。利用matlab遗传算法和solvopt算法工具包。不懂使用方法可以加我qq13319810(Cross-coupled quasi-elliptic function filter coupling coefficient of extraction procedures. The use of genetic algorithms and matlab toolkit solvopt algorithm)

无刷直流电机的建模和仿真，包含matlab里面的例子，可以仿真成功，有最后的转矩波形(Brushless DC motor modeling and simulation, including inside matlab example, can emulate the success, there is a final torque waveform)

ABAQUS有限元金属切削仿真模型(源自ABAQUS经典例题集三)(ABAQUS finite element simulation model of metal cutting)

说明：  MATLAB实现QR算法以及带位移的QR算法 求矩阵特征值(MATLAB，The realization of QR algorithm and QR algorithm with displacement Characteristic value of matrix)

资料中结合自身理解详细阐述了梅吉特译码的原理、梅吉特译码的电路以及matlab的仿真编码程序。(Information in detail with their own understanding of the principles of Meggitt decoding, Meggitt decoding circuitry and coding matlab simulation program.)

用于对文本的分类，并用于预测，达到一定的精确度。(in order to be use classify，and be used pretected,in order to be certain accuracy)
