说明：  洛伦兹方程的代码模拟程序和图像和一些文字说明。(Lorenz equations and image simulation program code and some text.)

极坐标下的分贝画图。matlab中极坐标画图函数为polar，但是无法画出转化为dB的图形，此函数为画db为单位数据的极坐标图形。(Db drawing in polar coordinates . matlab polar coordinate drawing functions for the polar , but can not draw dB graphics , this function graphics for painting db data in polar coordinates .)

matlab实现爱趣无穷控制，不错的，希望大家喜欢。(matlab infinite control to achieve love interest, good, hope you like it.)

主要用MATLAB对图像惊进行处理，对图像进行直方图处理 给出均衡前后的图形很有实用(Main MATLAB to image surprised processing, the image histogram equalization before and after the treatment given graphics is practical)

1．本程序演示的是用简单遗传算法随机一个种群，然后根据所给的交叉率，变异率，世代数计算最大适应度所在的代数 2．演示程序以用户和计算机的对话方式执行，即在计算机终端上显示“提示信息”之后，由用户在键盘上输入演示程序中规定的命令；相应的输入数据和运算结果显示在其后。 3．测试数据 输入初始变量后用y=100*(x1*x1-x2)*(x1*x2-x2)+(1-x1)*(1-x1)其中-2.048<=x1,x2<=2.048作适应度函数求最大适应度即为函数的最大值 (1. This program demonstrates a simple genetic algorithm is a random population, then according to the crossover rate and mutation rate, fitness for calculating the maximum number of generations in which algebra 2.

基于多相催化反应动力学的特点和基本原理,提出多相催化反应动力学方程的一般形式,并介绍了用Matlab语言设计确定多相催化反应动力学方程参数的通用程序.处理时先对实验测定不同时刻对应的反应速率v0和浓度C(或压力P),利用无约束最优化计算方法求出多相催化反应动力学方程参数.文中以镍硅藻土催化苯加氢合成环己烷的实验数据为例进行验证,结果表明,利用所编程序确定的动力学方程和理论值及文献值很好吻合.(Based on the characteristics and dynamics of the basic principles of heterogeneous catalysis, heterogeneous catalysis proposed general form of kinetic equation and introduces heterogeneous catalytic reaction kinetics equation to determine the parameters used in Matlab language design common procedures when handling the first experimental measured at different times corresponding to the concentration of the reaction rate v0 and C (or pressure P), the use of unconstrained optimization calculations obtained heterogeneous catalytic reaction kinetics equation parameters. text nickel diatomaceous earth catalytic hydrogenation of benzene cyclohexane an example to validate the experimental data, the results show that the equations and theoretical value and dynamics literature values ​ ​ determined using the programmed good match.)

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two improved Watterson models and Pseudo- Deterministic model. As a deterministic model, Volger model basically describes the characteristics of HF wideband channel, but it also needs to be improved. The improvement of Vogler model is given in this paper.
