用Matlab的GUI界面设计滤波器人机界面，可选FIR、IIR等高通，低通，带通，带阻滤波器，手动设定好参数，可直观看到幅频特性曲线和相频特性曲线。(Using Matlab GUI interface design a filter interface, optional FIR, IIR high pass, low pass, band pass, band stop filter, the parameters are set manually, you can visually see the amplitude-frequency characteristic and phase-frequency characteristic curve .)

使用matlab对卡尔曼滤波算法模拟，结果精确可用(Use matlab on the Kalman filter algorithm simulation results available)

说明：  matlab，实现永磁同步电机调速。pid控制(matlab pmsm pid controller)

巴特沃特带阻滤波器的设计，返回分子分母多项式系数，还可以作出增益曲线，以及求出相位响应以及群延时响应(Batewote band stop filter design, the return of molecular denominator polynomial coefficients, can gain curve, and the calculated phase response and group delay response)

非线性拟合,用于非线性拟合时，可以用这个现成的代码，很发方便！(Nonlinear fitting for nonlinear fitting, you can use the existing code, it is made ​ ​ easy!)

本程序主要通过二维经验模态分解计算二维信号的IMF，使用筛选的过程。它依赖于函数SIFT。(BEMD This program calculates the Bidimensional EMD of a 2-d signal using the process of sifting. It is dependent on the function SIFT.)

说明：  二次规划问题和MATLAB函数quadprog的使用小结(Summary of quadratic programming problem and the use of Matlab function quadprog)
