matlab的核密度工具箱，非常实用，简单易用。(nuclear density matlab toolbox, very practical, easy to use.)

matlab 例程，很简单的且很容易理解的k-medoids聚类算法源代码(matlab routines, very simple and very easy to understand k-medoids clustering algorithm source code)

本实验的内容是无线楼宇数据传输仿真，分析915M的楼宇通信特性，建立楼宇数据通信系统的仿真模型，采用无线收发芯片NRF905，依据其性能参数来判断楼宇内两点能否进行数据传输(the contents of this experiment is building wireless data transmission simulation, analysis 915M communications characteristics of the buildings, establishing building data communications system simulation models, the use of wireless transceiver chip NRF905. based on its performance parameters to judge whether two buildings for data transmission)

一种用matlab，在无线系统中有中继转发和时间关联性的并且有重传系统的outage的方法(One kind of use matlab, in a wireless system with relaying and time correlation and there retransmission system outage methods)

matlab数学手册，包括了矩阵计算，数理统计等方面常用函数和函数说明(matlab mathematics manuals, including a matrix calculation, mathematical statistics and other commonly used functions and function description)

此程序是matlab中给出矩阵均值的程序，注释详尽，使用简单，其中的注释详细，自己可以对变量做相应的变换(This procedure is given in matlab matrix mean the procedures, the Notes detailed, easy to use, which notes in detail that they can make the corresponding change of variables)

这6个程序可用于0—9的数字识别，算法包括：基于类中心的欧式距离法、马氏距离法、夹角余弦距离法 、二值化的夹角余弦距离法、二值化的Tanimoto测度法和增量校正算法，均为基于matlab软件编写的程序。学会了这几个算法，可以在这些程序的基础上进行扩展，对三维模型识别算法的编程有一定的帮助。(6 program can be used 0-9 digit recognition, algorithms include: class center Euclidean distance, Mahalanobis distance method, the cosine of the angle distance method, the cosine of the angle distance method binarization, binary of Tanimoto Measure Method and incremental correction algorithms are written based on matlab software program. Learned these algorithms can be extended on the basis of these procedures, programming algorithm of the three-dimensional model to identify some help.)

极有用的数据处理程序，方便处理实验数据，并取得数学表达式(matlab)(very useful data processing procedures, facilitate the processing of experimental data and mathematical expression made (Matlab))
