数学建模：最短距离和模拟退火 已调试好(The shortest distance and simulated annealing)

利用非线性控制完成光伏并网逆变器的设计，设计中采用模糊控制和反步法，介绍很好。(Using nonlinear control to complete the design of the photovoltaic (pv) grid inverter, adopted in the design of advanced reverse moves, the introduction is very good.)

MATLAB的编程，用于哈弗曼码的编码和解码，希望会对你用途啊(MATLAB programming for Havermann code encoding and decoding, I hope you will use ah)

基于MATLAB的AR模型的仿真，并分析功率谱，比较好。可以运行(AR model based on MATLAB simulation, and analysis of the power spectrum, the better. You can run)

time series In this example we will use a synthetic data set. To create our synthetic data we will make our unit of time 1000 years = 1 ky and sample a 500,000 year record in 2 ky increments. We first create a vector containing the times:
