实现图像灰度及黑白度转换,主要在matlab 环境下使用，具有很好的实用意义。(Gray and black and white image conversion degrees, mainly in the matlab environment, with good practical significance.)

MATLAB产生随机信号，计算相关函数，估计功率谱(MATLAB，random-signal，auto-correlation，power-spectrum)

用Matlab编写的Bayes 分类器，用以进行两类模式识别(prepared using Matlab Bayesian classifier, used for two types of pattern recognition)

基于matlab的OFDM仿真程序； 我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来.. 现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

BSM模型仿真，显示出不同指标的曲线图并且对比。(BSM model simulation, showing a graph of different indicators and contrast.)

从倒立摆的数学模型入手，对比了lqr控制器和pid控制器的设计和仿真(From the mathematical model of the inverted pendulum to start, compared to the design and simulation controllers and pid controller lqr)

说明：  matlab下模式识别分类后的统计，画图，简单，通用。(matlab classified under the statistical pattern recognition, drawing, simple, common.)

简单的信号处理程序,可以实现基本的z反变换。程序本身自带数据产生功能。(a simple signal process program)

可用于拟合化学分析中的一元线性回归并绘制残差图，找出可疑数据，对化学分析工作者很有用！(Caculated the linear degree and residues of all values you got.Very important for the chemical engineers and scientists.)
