最小二乘拟合，kf

仿真通信系统中QPSK的码头代码，大家可以作为参考(Simulation of Communication Systems pier QPSK code, we can serve as a reference)

rs编码的matlab程序，很详细，方便初学者学习(rs encoded matlab procedures, very detailed, easy for beginners to learn)

无刷电机电磁设计程序,包含空载和负载时的磁路工作点的校正(bldc design )

说明：  该函数用于用于拉格朗日插值的展开及其误差估计(matlab function for lagrane)

直接转矩控制源码，在simulink的环境下搭建的，绝对有效。可以直观的看到直接转矩控制的运行原理。(DTC control.)

用同步检波法解调DSBSC信号通信模拟调制仿真(DSBSC demodulated signal communication with analog modulation simulation synchronous detection method)

lte系统级仿真程序，很详细而且还有注释(lte matlab project)

说明：  利用FDTD方法模拟普通光子晶体光纤中模场变化的情况，为主程序，可以为学习FDTD模拟PCF的学习者提供一定参考和学习。(Ordinary FDTD simulation using photonic crystal fiber mode field changes in the situation, the main program, you can learn from FDTD simulation for the PCF to provide a reference of learners and learning.)

在对比度小的灰度图像中加入噪声，再对图像进行滤波和直方图均衡化，对图像进行增强，并比较了不同参数时的增强效果(In contrast, the gray image by adding a small noise, then the image filtering and histogram equalization of image enhancement, and compared the effect of different parameters of the enhanced)

example of matlab,optimization method which is used with different model.it will be useful for whom they want to learn Matlab by themselves1
