说明：  运用matlab进行模糊聚类分析步骤如下：建立数据矩阵；数据标准化；建立模糊相似矩阵；改造相似关系为等价关系；确定分类数(The steps of using MATLAB to carry out fuzzy clustering analysis are as follows: establishing data matrix; standardizing data; establishing fuzzy similarity matrix; transforming similarity relation into equivalent relation; determining classification number.)

matlab关于floyd算法的源程序，可以自由改变为所需的变量(matlab on the floyd mathemathica)

matlab中的主成分分析法，有效的计算了以后预测问题，精度高。(matlab in the principal component analysis, effective after the prediction calculated with high precision.)

本程序主要是针对一九杆结构进行的动力学分析，用newmark法，威尔逊法，状态空间法，子空间迭代法等求解了结构动态响应，并给出了图像显示(This program is mainly aimed at the structure of the 19 dynamic analysis, using newmark method, Wilson law, the state space method, subspace iteration method for solving the structural dynamic response, etc., and gives the image display)

在MATLAB编程语言环境下实现粗差的拟准检定法(In the MATLAB programming language environment to achieve gross errors QUAD method)

语音信息处理的好帮手，希望大家支持，非常感谢各位大侠(Voice messaging is a good helper, hope you will support, thank you heroes)

多目标BCC算法，在电力系统方面的具体应有，可套用( Specific examples of DBCC algorithm)

它通过对矩阵分解，相当于对矩阵做了正交化处理，方法我们进行信号检测信道估计等。(It can matrix factorization, the matrix made equivalent to orthogonalization processing, signal detection method we channel estimation.)

文字检测MATLAB程序 可以运行( word detection )
