使用matlab语言，实现了iForest算法。(In this case, i use matlab to realize iForest.)

孤立森林 是一个基于Ensemble的快速异常检测方法，具有线性时间复杂度和高精准度，是符合大数据处理要求的state-of-the-art算法(Isolated forest is a fast anomaly detection method based on Ensemble. It has linear time complexity and high precision. It is a state-of-the-art algorithm that meets the require

iforest算法可以进行对时间序列中异常的一段时间进行检测，算法非常高效(Iforest algorithm can detect abnormal periods in time series, and the algorithm is very efficient.)
