电压暂降正周期有效值,是四案例工程中比较常见的算法。(t=0:0.0002:0.2 y=cos(100*pi*t) y1=0.5*cos(100*pi*t) y(200:600)=y1(200:600) for i=1:1:901 u(i)=sqrt(sum(y(i:i+99).^2)/100) end plot(u) xlable( 采样点数 ) ylable( u ) )

GPS和INS组合导航程序，基于混沌的模拟退火算法，进行逐步线性回归。( GPS and INS navigation program, Chaos-based simulated annealing algorithm, Stepwise linear regression.)

说明：  matlab开发的RBF、BP PID算法，已经过测试(matlab development of RBF, BP PID algorithm has been tested)

matlab MPC工具箱说明，英文比较详细(Matlab MPC toolbox instructions, English is a more detailed)

test_graph for matlab

说明：  里面有不少MATLAB学习课件,对新手很有帮助。(there are many study matiarial)

说明：  基于标准模型的人脸识别程序，里面有一些小程序。(Face recognition program based on the standard model, which has some small programs.)

近似熵是一种衡量衡量非线性时间序列复杂性的非线性动力学分析方法，其物理意义 为熵值越大，时间序列的自我相似性越低，序 列越复杂，反之序列自我相似性越高；并且样 本熵对于序列长度依赖弱，仅需较短的数据就 能够得到稳健的熵值，同时其计算不需对数据 粗粒化，具有较好的抗干扰能力 (Approximate entropy is a measure to measure the complex nonlinear dynamics of nonlinear time series analysis method, the physical meaning of entropy value is larger, the lower the self-similarity of the time series, the more complex the sequence, whereas sequence of self-similarity the higher and the sample entropy weak dependence for the length of the sequence, only shorter data can be healthy entropy value, calculated without data coarse-grained, with good anti-jamming capability)
