利用matlab进行信号采样（欠采样、过采样等）的源程序(Sampling the signal using matlab (less sampling, oversampling, etc.) of the source)

IIR design using matlab using all four types of iir filter

matlab应用源程序，只能采集，网络连接(matlab application source code, can collect)

粒子群算法计算飞机维修次数的源码，可以看看( U7C92 u5B0 u7FA2 u7E9 u7B09 )

根据目标覆盖范围的天线最优化设计，有详细的说明文件(Depending on the target coverage of the antenna optimum design, contains a detailed description of the file)

说明：  matlab小波包去噪举例，对初学者很有用的一个短程序(matlab wavelet packet denoising for example, very useful for beginners a short program)

Matlab混合编程编程，很好的学习混合编程的资料(Matlab code)

本案例通过对图像加入高斯噪声，利用sym4小波函数对该图像和信号进行三级分解，用小波阀值去噪的方法对该图像进行去噪，并给出了仿真结果。(This case through join Gaussian noise image, use the sym4 wavelet decomposition of the image and signal, the wavelet threshold to filter method for the image denoising is presented, and the simulation results.)

快速NCC(normalized cross correlation)算法实现。比matlab自带的normxcorr2 快10-20倍。在windows Unix环境下c语言，和matlab编译通过。(use Matlab on Windows or Linux or Mac OS X and want fast (exact, general-case) normalized correlation (NCC) code right now, then download it and enjoy the large performance gain over Matlab s normxcorr2 (demo included). For the brave (and/or masochistic) there is B), however, it is unlikely you will do better than the above. Thanks to Liang Jin for making the OS X binary (his performance comparison graph on a PowerPC). )

自适应中的牛顿法。结论，当u靠近0.5时，wk 迅速增加到最佳权， 当u小于0.5时，wk 沿着一个方向单向靠近最佳权；u大于0.5时wk沿着起始点指向最佳权的方向左右振荡并向最佳权收敛 ！ (The Newton method adaptive. Conclusion, when u close to 0.5, wk quickly right to the best, when u is less than 0.5, wk along the a direction close to the best the right way u greater than 0.5 wk point along the starting point about the best direction for the right to the right of oscillation and convergence of the best!)
