本内容为，三维模型直接导入matlab中，可以方便的运行，可以更观的体现模型的真实性(This content is, three-dimensional model directly into matlab, you can easily run, you can view more manifestation of the authenticity of the model)

可以用来进行信用风险预测的matlab代码，直接模仿就可以用了(Can be used for credit risk prediction matlab code, you can use a direct imitation)

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 letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)
