这是我学习时候，我的课本上的课后习题，我把他整理出来！希望大家能有所收益！(This is my study, my after-school textbook exercises, I took him out of order! Hope that we can get any benefit!)

本手册介绍matlab中各种函数的应用，对matlab使用者帮助很大(This manual describes the application of various functions in matlab, matlab users of great help)

matlab编写的多元变量最小化问题的downhill方法求解(Matlab prepared by the multi- variable minimization problem solving methods downhill)

计算视频图像中每一帧的能量,matlab 代码，可以用于分析图像原能量与编码解码后，误差与原图像能量的倍数关系(computing the energy of each frame in image processing)

基于MATLAB的各种图像处理源码集，在.m文件里把图片名修改为本地电脑的图片即可运用。(The various kinds of image processing based on MATLAB source code)

多种群遗传算法的函数优化算法，可以实现基于多种群遗传算法的函数最优化问题(Multi population genetic algorithm function optimization algorithm, can be achieved based on multiple population genetic algorithm function optimization problem)

各种图像融合性能评价参数，包括D,MSE,PSNR,SF,RMSE,NCD,REL,MI,MAE,DREL,EOG,CREF等(Image fusion performance evaluation of various parameters)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

隔振 减震 原理 描写了隔振方面的理论并且通过几个例子描述了简谐振动(The principle of isolation damping describe the isolation theory and describe a few examples of a simple harmonic motion)
