说明：  一个针对高光谱图像进行主成分分析的小程序，但要求高光谱图像的格式是.mat格式。(For hyperspectral image of a principal component analysis of small programs, but requires the format of hyperspectral images. Mat format.)

公共汽车悬挂系统模型的MATLAB仿真程序,完成悬挂控制系统的研究(bus suspension system model MATLAB simulation program, complete suspension control system research)

This control system has been successfully applied in some 750mm hot strip mill. The actual record curves indicate that the dynamic feedforward strategy can do well in controlling the tail temperature. And the FuzzyPI-Smith system can get better dynamic characteristic and effectively overcome the problems by pure lag with the traditional

本程序可实现对一维信号的压缩感知ROMP重构(This program can be realized on the perception of one-dimensional signal compression reconstruction ROMP)

说明：  数值分析中的样条插值算法，通用举例。数值分析中的样条插值算法，通用举例(Numerical analysis of the spline interpolation algorithm, common example. Numerical analysis of the spline interpolation algorithm, for example general)

根据信号的时域表达式，在matlab中求出他的自相关函数，并绘画出来(correlation spectrum)

emd经验模态分解，适用于对含噪信号处理，优于小波去噪的信号去噪方法。(Empirical mode decomposition)

说明：  针对一般的粒子群优化(PSO)学习算法中存在的容易陷入局部最优和搜索精度不高的缺点,对改进型PSO算法进行研究。由于惯性权重系数ω对算法是否会陷入局部最优起到关键的作用,因此,通过改变惯性权重ω的选择,对惯性权重系数采取线性减小的方法,引入改进型的PSO算法。采用改进的PSO算法对PID控制器进行参数优化并把得到的最优参数应用于控制系统中进行仿真。仿真实验结果表明:改进型PSO算法不会陷入局部最优,能得到全局最优的PID控制器的参数,并使得控制系统的性能指标达到最优,控制系统具有较好的鲁棒性。(Aiming at the shortcomings of general PSO learning algorithm, which is easy to fall into local optimum and low search precision, the improved PSO algorithm is studied)
