这是一个用matlab模仿的地球同步卫星发射过程。是我学习matlab时编的，希望可以帮助理解matlab编程。(This is an imitation using matlab geosynchronous satellite launch process. I am prepared to learn matlab, and I hope can help understand the matlab programming.)

变频仿真，实现无级调速仿真功能，适合新手。(Frequency Simulation)

The ULIB is a collection of efficient building blocks for developing high-performance and scalable systems in C and C++. These building blocks mainly cover, multithreading, parallel computing, efficient data indexing, numerical approximation, and cryptography.

层数N对光子晶体带隙的影响，不同的介质层数N，即不同的周期数,传输矩阵也不同，光子晶体的反射率和透射率也不同。(Influence of layers N bandgap of photonic crystals)

光伏的数学通用模型。 工程用途，我参考搭建的模型 可以使用。(Universal mathematical model of PV. Engineering purposes)

this is a useful method of realizing prony in matlab system

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

基于分段非线性权重值的Pso算法，实现典型相关分析，是机器学习的例程。( Based on piecewise nonlinear weight value Pso algorithm, Achieve canonical correlation analysis, Machine learning routines.)
