说明：  实现的是数据挖掘的apriori 算法，用的是matlab算法，数据和算法比较简单(Implement the apriori algorithm data mining, using a matlab algorithm, data and relatively simple algorithms)

A method is presented for augmenting an extended Kalman filter with an adaptive element. The resulting estimator provides robustness to parameter uncertainty and unmodeled dynamics.(A method is presented for augmenting an ext Kalman ended with an adaptive filter element. T he resulting estimator provides robustness to parameter uncertainty and unmodeled dynamics .)
