Engineering and Scientific Computations Using MATLAB

说明：  能够很好的实现混沌数字水印技术 并且具有创新功能 (Can achieve the chaotic digital watermarking technology and innovative features)

用多尺度卡尔曼滤波法，对信号参数进行识别估计。高频信号和低频信号识别结合起来改进了算法识别的精确度和准确度。(It is an implementation of hierarchical (a.k.a. multi-scale) Kalman filter using belief propagation. The model parameters are estimated by expectation maximization (EM) algorithm. In this implementation, we considered two time series with different frequencies. The messages between high and low frequency signals are combined to improve the estimation and prediction.)

matlab画图时，在查看图上大数据时将数据显示为8位有效位。(matlab drawing, in view large map data to display data as 8-bit valid bit.)

Small signal stability analysis of a multi machine system

说明：  matlab的入门，金典书籍，值得一看。对于新手或刚入门的有很多帮助(matlab entry, Jindian books, worth a visit. For novice or just a lot of help getting started)

产生正弦波 的matlab源程序 小弟第一次做的程序 不知对大家有用吗?(generated sine wave of Matlab source younger the first time in the process we do not know right useful?)

无线传感器LEACH算法，可以用matlab来仿真LEACH路由协议(LEACH program for matlab)

说明：  基于matlab运用最小二乘法对信号进行消除趋势项处理以及五点三次平滑法对信号进行平滑处理，消除毛刺等(denoising vibration signal based on matlab)
