butterworth高通滤波器的原程序，可用ＭＡＴＬＡＢ的ＦＩＬＴＥＲ函数测试．可得到高通滤波器数字系统函数的系数．(Butterworth high-pass filter the original procedure, MATLAB can be used to test the FILTER function. Available high-pass filter function of the coefficient of digital systems.)

this is matlab code for estimating the static linear system(system function is time variable) with Recursive Least Squre and 2 solutions for better result. 1- using the Covariance Matrix Reseting in a specefic time. 2-using the RLS with Forget Factor this program is written by matlab 7.0. Here we want to estimate the below function: 1-u^2+(1+tansig(0.1*(t-375)))*u^3+u^5+3*u^7 finally,there are plots for showing results.

Fit calculates coefficients c of the least-squares approximating polynomial

说明：  一个简单的SPM传播模型仿真，可以手动进行校正(SPM model)

attached file contain two algorithm for classification.K_means and K Nearest Neiborhood. and related m_filles in matlab

说明：  根据滤波器指标选择合适的窗函数，计算窗函数的长度N，调用MATLAB函数fir1设计一个FIR低通滤波器。并编写程序，调用MATLAB快速卷积函数fftfilt实现对xt的滤波。绘图显示滤波器的频响特性曲线、滤波器输出信号的幅频特性图和时域波形图。  (Select the appropriate indicators according to filter window function, calculate the length of window function N, called MATLAB function fir1 design a FIR low-pass filter. And programming, call MATLAB functions fftfilt achieve fast convolution filtering xt. Graphics filter frequency response curve, the filter output signal amplitude and frequency characteristics of maps and time-domain waveform.  )
