控制领域非常棒的书，搞控制的必须学习。针对Design for Underactuated and Nonlinear Marine Systems，Khac Duc Do • Jie Pan这两个人必须知道！(Researchers Khac Duc Do and Jie Pan have published a sequence of journal and conference papers on new control algorithms for underactuated systems.)

用于结构在动力荷载作用下的时程分析,地震荷载，随即荷载均可，采用newmark方法(For structural time history analysis under dynamic loads, seismic loading, then the load can be, using the newmark method)

通过确定执行边界的方法计算美式期权价格，并画出它的执行边界。(Determine the implementation of the boundary of the method to calculate the American option price and draw the boundary of its execution.)

语音是人类交换信息的有效渠道之一，也是我们日常生活交流的主要形式。 语音与当今科学技术的快速发展息息相关，特别是计算机中的语音交互技术，通 过对语音信号进行采集和处理，实现人与人之间有效信息的传输、获取以及存储。 基于 MATALAB 的语音信号去噪设计，对噪声信号进行有效地滤除，将降噪后的语音信号与原始 信号在时域和频域进行对比分析，计算出信噪比，并在 MATLAB 中设计 GUI 仿 真界面进行展示.(Speech is one of the effective ways for human to exchange information, and it is also the main form of our daily life communication. Speech is closely related to the rapid development of modern science and technology, especially the voice interaction technology in the computer. Through the acquisition and processing of voice signals, the transmission, acquisition and storage of effective information between people and people is realized. Based on the noise signal de-noising design of MATALAB, the noise signal is effectively filtered, the speech signal and the original signal after the noise reduction are compared and analyzed in the time domain and frequency domain, and the signal to noise ratio is calculated, and the GUI simulation interface is designed in the MATLAB.)

说明：  关于定时同步的Matlab仿真代码，采用锁相环技术实现(Matlab code for Timing recovery using PLL)

一个追赶法文件.大家交流!c++编的matlab程序.我们研究生作业!数值分析.比较简单.希望大家批评指正! (a chasing documents. Exchange! C addendum to the Matlab procedures. We postgraduate work! Numerical pm Analysis. relatively simple. We hope that the criticism corrected!)

2D version of Brownian motion. A random walk is similar to markov process, however a markov process has no memory, where a random walk uses an initial state. The next step in the walk does not necessarily depend on your current state but will be referenced from your current state, that is to say the random vector is added to your current state. depending on complexity
