interesting and easy C++ application for beginers

Stochastic resonance，SR）的概念最初是由Benzi等人提出并用于解释第四纪冰川问题，此后用于描述一种现象──非线性系统中内噪声或外噪声的存在可以增加系统输出的响应。这里一共有在网上下载的一共7种不同的程序，供大家分析参考(The concept of Stochastic resonance (SR) was first proposed by Benzi et al. And used to explain Quaternary glaciation. After that, it is used to describe a phenomenon -- the presence of internal noise or external noise in nonlinear system can increase the response of the system output. There are a total of 7 different programs available for download on the Internet for people to analyze and refer to)

说明：  通过编程得到正交的1egendre(N)函数序列(Orthogonal sequence of Legendre (N) functions obtained by programming)

说明：  fastica实测数据，可以做数据的预处理，保留有用信号，滤除噪声(FastICA measured data, can do data preprocessing, retain useful signal, filter noise)

天在维普下载了一篇SPIHT算法改进的论文，（耿兴云，《基于改进SPIHT的静态图像编码》，电脑知识与技术：学术交流-2007年5期），我根据该文提出的改进算法，用Matlab来实现，却发现改进算法的程序运行速度比原算法还要慢，希望有兴趣的朋友进来看看，评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)

经验模态分解(Empirical Mode Decomposition,EMD)法是黄锷(N. E. Huang)在美国国家宇航局与其他人于1998年创造性地提出的一种新型自适应信号时频处理方法，特别适用于非线性非平稳信号的分析处理。(Empirical Mode Decomposition)

说明：  是建议光纤模型的程序，和comsol相关的程序，并引入边界条件(it s about the codes for the model of optical fiber,connecting with thes software comsol. the boundary is involved)

model predective control system design and implementation using matlab

这是基于约束最大期望算法的matlab程序，对参数估计及图像分割有较大作用(This is based on expectations of the biggest constraint algorithm Matlab procedures, parameter estimation and image segmentation greater role)
