计算输入信号的功率谱密度和估计输入信号带宽并绘图(Evaluation of the single-sided ESD and frequency bandwidth)

说明：  详细研究了单级倒立摆起摆控制方法，并给出了详细的仿真模型与仿真效果(Detailed study of the single inverted pendulum swing-up control method, and gives a detailed simulation model and simulation results)

霍夫变换的源程序，专门用于复杂背景下圆孔的中心定位(Hough transform of the source, specifically for the complex context of the central positioning hole)

分析电力系统风电出力数据的状态转移概率。在得到两三年的风电场发电出力数据后，可用该程序分析风电出力的具体变化，以及风电出力在相邻时刻不同状态之间的转移概率。(Analysis of power system wind power output data state transition probabilities. In two or three years to get the wind farm power output data, the program can analyze specific changes in wind power output, as well as wind power output in the adjacent time transition probabilities between different states.)

说明：  matlab中用simulink模块实现qpsk调制，包括模块及其主函数 (matlab with simulink module QPSK modulation, including the module and its main function)

说明：  矩形波函数，计算其频谱，幅度谱和相位谱，与理论值比较。(Rectangular wave function to calculate the frequency spectrum, amplitude spectrum and phase spectrum, compared with the theoretical value.)

matlab 的simulink快速入门，老师总结的，对初学者很有帮助( learning of simulink)

BPSK_QPSK LDPC基于MATLAB编译码仿真程序(BPSK_QPSK LDPC)

说明：  可以对数量少、残缺、不完整的数据进行预测，如人口、缺水量等。也可以对灾害发生时间进行预测。(Can be a small number, mutilated, incomplete data to predict, such as population, water shortage and so on. You can also predict the time of occurrence of the disaster.)

在数学建模培训中，降落伞问题很是突出，联系此题对同学有很大的提高，从而程序也很重要。所以发此文件。(Parachute Su snow modeling program title race body)
