多输入多输出的小波网络模型，需安装matlab神经网络工具箱用的是青岛海洋大学学报上那篇论文的模型,嵌入了开发的初始化算法，程序里有较为详细的说明，很好用(Multiple-input multiple-output wavelet network model, the need to install matlab neural network toolbox is used Qingdao Ocean University Journal article thesis model, embedded in the development of the initialization algorithm, the procedure has a more detailed explanation, very good use)

说明：  蚁群聚类优化算法Matlab代码,基本原理和思路(Matlab code for ant colony clustering algorithm, the basic principles and ideas)

一个用BoW|Pyramid BoW+SVM进行图像分类的Matlab Demo (Image Classification using Bag of Words and Spatial Pyramid BoW)

实现了31位m序列，并采用相关解扩,有传统和倒置两种方法(31 m sequence )

对于数据的丢失用不同的方法进行补缺，并且对不同的补缺方法进行了比较(Filled, for the loss of data in different ways, and a comparison of different methods to fill)

稀疏快速傅里叶变换，是一种利用信号频域稀疏特性，只需通过信号部分采样点就可高概率恢复信号频谱的快速傅里叶变换算法。(Sparse Fast Fourier Transformation ，SFFT)

Neural Network in basic matlab

根据过渡带宽及阻带衰减要求，选择窗函数的类型并估计窗口长度N（或阶数M=N-1），窗函数类型可根据最小阻带衰减As独立选择 (According to the transition bandwidth and stopband attenuation requirements, select the type of window function and estimate the window length N (or the order of M = N-1), type of window function according to the minimum stop-band attenuation can be independently selected As)
