代码说明:

  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)

    《MATLAB6.0数学手册》 本教程按逻辑编排,自始至终用实例描述,既适用于初学者自学,也适用于高级 MATLAB 用户。可作为高等数学、数值分析、工程数学、数学建模、线性规划等课程的教 学参考书,也可作为科技工作者学习和使用MATLAB 的参考书,还可作为数学实验的教学 用书,特别适合用作理工科大学生学习数学课程的教学辅导书。(" MATLAB6.0 Mathematics Handbook," this tutorial logically arranged from beginning to end examples describing both self-study for beginners, but also to advanced MATLAB users. Can be used as advanced mathematics, numerical analysis, engineering, mathematics, mathematical modeling, linear programming courses teaching reference books, but also can be used as scientific and technological workers to learn and use MATLAB reference books, but also as an experimental teaching mathematics books, in particular, suitable for science and engineering students to study mathematics curriculum counseling books.)
