PDESELECT 手动选择和移动操作的图形界面偏微分方程工具(PDESELECT manually select and mobile operations graphical interface tool for partial differential equations)

说明：  最优化算法，使用信赖域法（LM）求解无约束问题。可以实现画出三维图像，通过修改初始点，得到迭代次数和函数值(Optimization algorithm, using LM method to solve unconstrained problems. Three dimensional images can be drawn, and the number of iterations and function values can be obtained by modifying the initial points.)

matlab基本差分进化算法，仅供参考，包括种群变异，交叉、选择生成下一代种群的过程(matlab basic differential evolution algorithm, for reference, including the population variation, crossover, select the process to generate the next generation of population)

无线衰落信道 在无线移动信道中，信号从发射天线经过复杂的传播环境到达接收天线，接收信号为各反射、衍射和散射分量以及信道噪声的复合，因而会产生严重的失真。另外，移动信道中由于移动台运动或信道环境的改变会使信道特性随时间随机变化，接收到的信号由于Doppler效应会产生更为严重的失真。 (OFDM has superior performance when transmitting high rate data in wireless fading channel.)

用matlab实现的往plot中添加color bar 的例子程序(add color bar to plot using matlab)

用matlab进行图像处理的相关函数，可进行图像的处理，不用自己写函数了(Image processing using matlab function, image processing, do not write your own functions)
