matlab讲座,跟数学建模相关，应该很有用吧 (Lecture of matlab，relating to mathematical modeling, hope it useful)

word document which describes how to generate direct sequence spread spectrum signal.

说明：  本程序为改进后matlab的空时分层码的仿真算法，能直接实现(The procedure for the improved layered space-time codes matlab simulation algorithm can be directly implemented)

本人通过MATLAB编写的代码，用于图像识别和语音识别，基于端点检测和基于rtKQMu和bbrIpro的孤立词识别和连续语音识别，是我的毕设代码。 (I have written the code in MATLAB for image recognition and speech recognition, endpoint detection and isolated word recognition and continuous speech recognition based onrtKQMu and bbrIpro, it is my complete set of code. )

可转债论文，研究定价，模型，方法，赎回，回售等(This thesis is devoted to evaluating two-factor convertible bonds. Di® erent zero- coupon bond curves are inputted when evaluating convertible bonds issued by com- panies with di® erent credit ratings. Thus the e® ect of the company s credit on the price of the convertible bond is easily and accurately included during the computa- tion. In the model for the interest rate, the parameters in the variance are determined from the market data by statistics and the market price of risk is determined by a zero-coupon bond curve through solving an inverse problem. When we price the con- vertible bond, a free-boundary problem is solved. A Singularity-Separating Method (SSM) is proposed in order to solve this problem e±ciently. Taking the market data)

Matlab basics are explained to brief the concepts in details

C. Torrence博士在分析厄尔尼诺现象时的示例程序，包含小波的重构部分，非常经典，该文被引用超过2400次(C. Torrence Dr El Nino phenomenon in the analysis of the sample program, including reconstruction of part of the wavelet, very classic, the paper cited more than 2400 times)

对正弦信号进行简单的频谱分析，变换采样频率和信号持续时间(A simple sinusoidal signal spectrum analysis, changing the sampling frequency and signal duration)

SAR range-poppler algorithm

The AES algorithm has implemented for bitplane images using RC4 algorithm.RC4 is called as Rivest Cipher 4 for encrypt and decrypt an image.It is used here preserve the image content data hacking. Here, the implemented code has tested with MATLAB2010a for Default MATLAB grayscale images.
