说明：  一种新的端点检测方法，对学习语音识别有一定帮助(A new endpoint detection method, has certain help to the study of speech recognition)

通过MATLAB工具箱对pcm的13折线法量化编码译码过程仿真(MATLAB toolbox pcm by 13 line coding and decoding process simulation method to quantify)

说明：  基于小波变换模极大的多尺度图像边缘检测matlab源代码，该算法采用的是样条小波，为了更好的检测边缘，用多孔算法代替了mallat算法。该算法和mallat快速算法主要区别： 1 多孔算法不需要抽取偶数样本，所以奇异检测定位更准确，相应的重构是不需要插零。2 多孔算法需要对滤波器进行伸缩。(based on wavelet transform modulus maxima of multiscale edge detection Matlab source code, The algorithm used is kind of wavelet, in order to better detect the edge of porous algorithm instead of Mallat algorithm. The algorithm and fast algorithm Mallat major difference : an algorithm porous not even take samples So singular position detection more accurate, the corresponding Reconstruction interpolation is not zero. Two porous algorithm need to filter extendable.)

说明：  能够实现Simulink 简单的pm调制解调(Implementation of Simulink PM modem)

采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤波(2D median filtering function medfilt2 right by the Salt and Pepper noise image filtering)

多用户OFDM系统的子载波分配算法参考论文(Subcarrier allocation algorithm for multi-user OFDM system)

先对陀螺仪测量数据进行预处理，每隔100行抽取一行数据，以第7列数据为例，用ALLAN方差法分析出五项主要参数(First gyroscope measurement data preprocessing, extract a row of data every 100 rows, seven of data, for example, ALLAN variance analysis of the five main parameters)

几个UKF和EKF例子，本来在工具箱中附带，后经修改，以便易于理解和适应稍有不同的需求。(several UKF and EKF demos,which were attached with KF toolbox, and revised according to tracing purpose.)

偏微分方程的MATLAB解法,主要介绍非线性方程组求解方法,给出不同方法的数值解法。(MATLAB Solution of partial differential equations, describes the nonlinear equations solving methods, given the different methods of numerical solution solution.)
