卡尔曼滤波是解决以均方误差最小为准则的最佳线性滤波问题，它根据前一个估计值和最近一个观察数据来估计信号的当前值。而本程序是利用matlab实现卡尔曼滤波-Kalman filter is the solution to the minimum mean square error criterion optimal linear filtering problem, which according to the previous estimate and the most recent observational data to estimate the current value of the signal. The realization of this program is to use the Kalman filter matlab
