HMM在Matlab下的程序，包括源文件和Demo以及Hmm相似度的计算程序-HMM in Matlab, the following procedure including the source documents and Demo Hmm similarity and the computational procedures

测试文本，选用著名的gettysburg这篇英文文本做为测试文本-Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of let

最后的测试程序，得出文本检索的正确率和召回率-In the end, the cosine similarity of texts is used to measure the similarity between the query and documents. The data comparison indicates that this algorithm has well experimental results. Moreover, it gets the advantage over
