LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

高斯积分，可以实现任意区域上的平面二重积分，可以带有参数。精确度高，希望对大家有用！(Gaussian integration can be achieved on any area of ​ ​ the plane of the double integral with parameters. Accuracy, we hope to useful!)
