说明：  现代通信系统MATLAB源码（刘树棠）教材配套，可以和书籍配套使用，效果很不错。(Modern communications systems MATLAB source code (刘树棠) supporting materials, and books can support the use of, the effect is pretty good.)

混沌与分形理论是最新兴起的金融市场理论，这是混沌与分形分析的例程，需要的请自行下载(chaos and fractal theory is the latest emerging financial market theory, which is chaotic and fractal analysis routines. Requests need to download)

Only coding parameters of sound generation model • LPC is an example where parameters are a1, a2, …ak , e(n) • Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency and amplitude is present, then other tones or noise of similar frequency cannot be heard by the human ear • the louder tone (masker) makes the softer tone The Masking Threshold is used by the audio encoder to determine the maximum allowable quantization noise at each frequency to minimize noise perceptibility: remove parts of signal that we cannot perceive

it is about binary phase shift keying

make the simple game of life. it only uses 50 X 50 size of point and time limited system.

In the computer science field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems.[1] Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover. Genetic algorithms find application in bioinformatics, phylogenetics, computational science, engineering, economics, chemistry, manufacturing, mathematics, physics, pharmacometrics and other fields.

不考虑不平衡磁拉力（UMP），转子系统在自身的质量、阻尼、弹簧等作用下，轴心轨迹求解方法(unbalanced magnetic pull is not considerated and rotor center orbit is gotten)

假设微电网中有风、光、微型燃气轮机、蓄电池，且已知各时段负荷需求；考虑各机组运行成本、燃料成本、与污染物处理成本。该程序可解决在孤岛运行模式下，各机组出力如何分配才能达到经济最优的问题。(It is assumed that there are wind, light and micro gas turbines and batteries in the microgrid, and the load demand is known at each time period. The operation cost, fuel cost and pollutant disposal cost of each unit are considered. This program can solve the problem of how to allocate the power of each unit in the mode of island operation to achieve the best economy.)
