求出laguerre滤波器的分子分母系数，绘出其幅频响应图并与FIR滤波器作比较。该程序为19阶Laguerre低通滤波器和22阶带通滤波器(obtained laguerre filter coefficient of molecular denominator, chart its amplitude frequency response plans with the FIR filter for comparison. The procedure for the 19-Laguerre low-pass filter and 22 band pass filter)

输入交指结构滤波器所要求参数，包括中心频率，相对带宽，带外抑制，球的交指滤波器参数(Input interdigital structure required by the filter parameters, including the center frequency, the relative bandwidth, band rejection ball interdigital filter parameters)

基于Matlab的数字水印算法的实现程序，很好很强大(Watermark)

系统系统辨识文件夹内是产生高斯白噪声，m序列和最小二乘法的一次完成算法，递推算法，限定记忆法的程序。系统仿真文件夹内是对系统线性和非线性的建模和仿真程序。(System folder on system identification is to generate Gaussian white noise, m sequence and a complete least-squares method algorithm, recursive algorithm, limited memory method procedures. System Simulation System folder is a linear and nonlinear modeling and simulation program.)

基于电力系统中的潮流编写的电力系统回路阻抗法 以更好的解决电力系统中的潮流问题(Based on the trend of power system loop impedance power system written law in order to better solve the power system of the power flow problem )

主成分分析代码， 可以用于图像压缩等等，也叫PCAH或者KL变换(PCA or K_L transfer)

matlab与CC++混合编程程序，可以参考下，适合初学者(matlab and C C++ mixed programming program, you can refer to, for beginners)

matlab code for Meijer function

把整个频率范围中的某段重点频区局部放大，获得比整个频率范围高的频率分辨率，从而观察频谱中的细微部分(The entire frequency range of the frequency of certain key areas enlarged to obtain the entire frequency range than the high frequency resolution, and thus observe the subtle part of the spectrum)
