it is the matlab code of particle swarm optimization with a test function that can be change..

说明：   捷联惯性导航的卡尔曼滤波 初始对准程序(SINS initial alignment procedure of Kalman filtering)

说明：  matlab程序模拟微分方程。各种流行的系统显示混沌运动特征。(This toolbox contains the functions which can be used to simulate some of the well-known fractional order chaotic systems, such as: - Chen s system, - Arneodo s system, - Genesio-Tesi s system, - Lorenz s system, - Newton-Leipnik s system, - Rossler s system, - Lotka-Volterra system, - Duffing s system, - Van der Pol s oscillator, - Volta s system, - Lu s system, - Liu s system, - Chua s systems, - Financial system, - 3 cells CNN. The functions numerically compute a solution of the fractional nonlinear differential equations, which describe the chaotic system. Each function returns the state trajectory (attractor) for total simulation time. )

Matlab 程序语言，有jacobi GS迭代，弦截法等。(Matlab programming language, there jacobi GS iteration, Secant method.)

在每一次小波变换中，都提取其中的“逼近信号”作为下次变换的输入，同时忽略掉其中的“细节信号”，即清除一次信号中包含的高频噪声分量。变换后的输出信号与原始信号相比，噪声起伏明显改善。(In every wavelet transform are extracted one of the " approximation signal" as the input of the next change, while ignoring one of the " details of the signal" , that is, a clear signal contains high frequency noise components. Transformed output signal compared with the original signal and noise fluctuations significantly improved.)
