MATLAB下用最小二乘设计低通，高通，带通，带阻数字滤波器。(Using MATLAB m-file to design LP, HP, BP and BS fitlers based on Least-square algorithm.)

说明：  同步电机模型的MATLAB仿真。。本文针对同步电机中具有代表性的凸极机，在忽略了一部分对误差影响较小而使算法复杂度大大增加的因素（如谐波磁势等），对其内部电流、电压、磁通、磁链及转矩的相互关系进行了一系列定量分析，建立了简化的基于abc三相变量上的数学模型，并将其进行派克变换，转换成易于计算机控制的d/q坐标下的模型。(MATLAB simulation of synchronous machine model. . Synchronous motor in this paper, salient pole machine with a representative, in the neglected part of the error is less impact on the complexity of the algorithm greatly increase the leaving of factors (such as the harmonic magnetic potential, etc.), its internal current, voltage, magnetic flux, flux and torque relationship between a series of quantitative analysis, a simplified three-phase abc variables based on the mathematical model, and the Park transformation, into easy-to-computer control of the d/q coordinate model .)

图像恢复（复原） 图像复原技术就是将图像退化过程模型化，并且采用相反的过程进行处理，以便复原出原始图像。例如，原始图像fig3_1.bmp由于退化变成了退化图像fig3_2.bmp。此图像的退化函数为： ，其中 ，M=366，N=364。请采用全逆滤波和不同截止半径的逆滤波对其进行复原，并与原图像fig3_1.bmp进行比较。再采用维纳滤波对其进行复原，并与逆滤波结果进行比较。 (图像恢复)

说明：  取u=0.0375，阶数L=11，比较w取不同值时LMS算法的运算结果之间所存在的差异(observing the diferent result of LMS when "w" is diferent (u=0.0375 and L=11))

TE化学过程的原始数据，对于MATlaber来说会是珍贵的数据啊 (TE chemical processes raw data for MATlaber the precious data.)
