Reinforcement Learning 中以 Q learning 學習的倒單擺實驗。以x,x_dot,theta,theta_dot作為狀態參數 state，利用model模擬之結果做Q值更新，產生Q table，對學習平衡控制。結果以csv檔作為輸出，可以由使用者作圖觀察變化。(Reinforcement Learning , utilize Q learning for An inverted pendulum system control。x,x_dot,theta,theta_dot as state variable，use model result renew Q table，control learning of balance pole 。output csv file contain trail(times),balance time(sec).it s better observe the change if user plot it. )

本程序详细区别了matlab中pca、svd、eig三个函数的区别和联系。对于学习pca有极大帮助(This program detailing the differences between the differences and connections in matlab pca, svd, eig three functions. Pca great help for learning)

进行航天器轨道运算经常用到的函数，包括坐标转换，经纬度转换，二体运动，轨道要素计算等等(For spacecraft orbit operations frequently used functions, including coordinate conversion, latitude and longitude conversion, two-body movement, and so calculated orbital elements)

在matlab中，基于GUI工具箱，实现了频谱分析仪的功能(GUI-based toolbox in matlab, the spectrum analyzer function)

本文主要介绍了功率谱估计中古典谱估计中的周期图法和现代谱估计中的 AR模型Burg算法，对这两种算法进行了原理说明，并对其进行了仿真，通过结果分析比较其优缺点。 (In this paper, power spectral estimate the Burg AR model algorithm in the the periodogram in classical spectral estimation method and the modern spectral estimation, the principle description of these two algorithms and compare their excellent analysis of simulation results shortcomings.)
