IIR滤波器的设计论文，基于MATLAB的设计。 希望它能对大家有一定的作用，谢谢！(IIR filter design paper, the design based on MATLAB. Hope that it will have some effect on you, thank you!)

粒子群算法以及优化后粒子群算法，可直接运行(Particle swarm optimization algorithm and particle swarm after, run)

利用MATLAB读取excel邻接矩阵数据，利用自带函数dist对路网共193个节点循环，求解任意两点间最短路径长度，输出结果是矩阵形式(a good way to calculate the shortest path between two points)

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。(constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.)

关于soft matting的MATLAB代码(A closed form solution to Natural Image Matting A. Levin D. Lischinski and Y. Weiss )

1、设计一个62阶低通滤波器，采样频率为9kHz，通带截止频率为3kHz，要求阻带最小衰减50dB。 2、将滤波器系数输出到txt文本文档。 (1, the design of a 62-order low-pass filter, the sampling frequency is 9kHz, passband cutoff frequency of 3kHz, requires a minimum stopband attenuation 50dB. 2, the output of the filter coefficients to txt documents.)
