量子计算函数，包括shor,grover等算法，非常方便(This document presents a brief tutorial/overview of QCF, then shows how it can be used to simulate the well-known algorithms of Deutsch, Deutch-Jozsa, and Grover. )

matlab 时频分析工具箱， 对于做时频联合分析很有用(time-frequency analysis matlab toolbox for doing time-frequency analysis is useful)

针对SVM法线特征筛选算法仅考虑法线对特征筛选的贡献,而忽略了特征分布对特征筛选的贡献的不足,在对SVM法线算法进行分析的基础上,基于特征在正、负例中出现概率的不同提出了加权SVM法线算法,该算法考虑到了法线和特征的分布.通过试验可以看出,在使用较小的特征空间时,与SVM法线算法和信息增益算法相比,加权SVM法线算法具有更好的特征筛选性能.(Normal feature selection for SVM algorithm only considered normal for the contribution of feature selection, to the neglect of the characteristics of the distribution of feature selection have contributed to the lack of normal SVM algorithm based on the analysis, based on the characteristics of the positive and negative cases emergence of a different probability-weighted normal SVM algorithm, which takes into account the distribution and characteristics of normal. through the test can be seen in the use of smaller feature space, the normal and the SVM algorithm and information gain algorithm, normal weighted SVM algorithm has better performance of feature selection.)

matlab读取uff文件数据 Universal file generation from I-Deas for Test can be split into two categories: export of model file data and export of adf data. It is not possible to write both sets of data to a single file. Written with a model file universal file are the geometry, elements and traceline data. However, just to add confusion, nodes and tracelines can also be written separately in their own file format.(Universal file generation from I-Deas for Test can be split into two categories: export of model file data and export of adf data.
