Kalman Filtering Matlab example

采用线性卡尔曼滤波估计阻尼简谐振荡器的速度和位置(demonstration of a Kalman filter estimating the state (position and velocity) of a damped harmonic oscillator with constant forcing.)

利用MATLAB程序中的inline和nlinfit两个命令对血药浓度-时间数据进行非线性拟合,求解血管外给药的药动学参数。同时与3P97软件计算结果进行了比较,结果表明,基于MATLAB程序可方便快速地求解血管外给药的各个药动学参数,计算结果与3P97软件计算值相当,且本方法操作简便、界面直观、易于推广,可用于临床教学或实验中药动学参数的计算。 更多还原 (Using MATLAB program inline and nlinfit two commands to the plasma concentration- time data by nonlinear fitting, solving the pharmacokinetic parameters of extravascular administration. Simultaneously with the 3P97 software to calculate the results were compared, the results show that can quickly and easily solve extravascular administration of various pharmacokinetic parameters based on MATLAB, the results calculated with 3P97 software fairly, and that the method is simple, intuitive interface, easy to spread, can be used to calculate the clinical teaching or experimental medicine pharmacokinetic parameters.

说明：  一个简单但是很有意思的代码。可以实现阳历和阴历的转换。并且能够查询阴历。(A simple but very interesting code. Can achieve the conversion solar and lunar calendars. And the ability to check the lunar calendar.)

根据给定时间序列求混沌特征参数的相关算法。(Chaotic Parameters given time series seeking algorithm.)

This is a MATLAB code (function) which elects two new nodes each time. Nodes are elected relatively to their distance in term of hop count to the initiator. This code is used by tree construction algorithm in networks modeled as weighted matrix.

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)
