现代通信系统，第五章，课后作业题目的MATLAB源代码程序(Modern communication systems, chapter, after-school job)

融合工具箱，有多种图像融合算法的MATLAB源程序，有总界面，操作简单，可直接进行仿真，非常好用(Fusion toolbox, there are several fusion algorithms MATLAB source code, there are always interface, simple and direct simulation)

用Runge-Kutta 4阶算法对初值问题按不同步长进行求解，用于观察稳定区间的作用。(With a four order Runge- Kutta algorithm for initial value problems in asynchronous long, used to observe stability range.)

改程序的功能：基于IMAGE混响模型编写的混响估计程序，条件实在矩形的房子中进行的(Change program features: based on IMAGE reverberation model reverberation estimation program written, just rectangular house)

说明：  充分利用估计误差的比例,积分,微分信号考虑一类线性系统的参数化观测器设计问题,在加快观测器收敛速度的同时避免较大的超调.从理论上分析此类观测器设计的可行性,并从实际应用角度给出一种简单可行的参数设计方法.仿真实验表明:该观测器不但易于实现而且能够获得较好的估计效果,从而有利于在实际工程中的应用.(In this paper, the proportional, integral and differential signals of the estimation errors are fully utilized to consider the design of the parameterized observer for a class of linear systems. The convergence speed of the observer is accelerated and the overshoot is avoided. The feasibility of the design of the observer is analyzed theoretically, A simple and feasible parameter design method is given from the point of view of practical application. Simulation results show that the observer is not only easy to implement, but also can obtain good estimation effect, which is conducive to the application in practical engineering)

说明：  Matlab编程，可用于对二维图像进行处理，得到相应的轮廓图、Sobel边界图、柱状图等，可以进行灰度调整 (This program is used for 2D image.It can be used to give the outline,Sobel bounadry map and histogram of the image.Also,it can ajust the gray of the image.)

分形差值函数是由迭代函数系统IFS实现的，通过离散的数据点构成分形插值函数，证明分形插值函数是这个IFS唯一吸引子。利用MATLAB矩阵运算，实现数据点的分形差值拟合。该算法简介直观。(The fractal difference function is implemented by the IFS fractal interpolation function through the data points of the discrete prove fractal interpolation function only attractor of the IFS. Fractal difference fitting using MATLAB matrix operations, the data points. The algorithms Profile intuitive.)

应用Matlab采用Galerkin法求解偏微分方程(Galerkin method for solving partial differential equations by matlab)

基于牛顿法，现采用编程来计算最优解，matlab程序和简要说明文档。(newton method for optimization)

应用Matlab计算边界条件，解决最优控制问题。(Matlab Boundary Conditions )
