该算法利用高效的索引方法，达到快速的匹配，解决了多序列的子序列匹配问题。
Using an efficient index method, people can get a fast matching, and have solved the subsequence matching of multi -subsequence.
返回以前匹配项的子序列。
替换字符串可能包含对在之前的匹配中捕获的子序列的引用。
The replacement string may contain references to subsequences captured during the previous match.
在各级子序列的匹配过程中，均先以趋势相似性为标准进行粗匹配，再以价格变化率的欧式距离作为相似性度量完成进一步的细匹配。
On each level, a rough matching base on trends similarity and a precise matching based on the Euclidean distance of price change rate will be executed orderly.
