itk是美国国家卫生部开发的图像处理程序，但是使用不便，所以制作了他的matlab接口(itk is the United States National Institutes of Health to develop image processing procedures, but the use of inconvenience, so the production of his matlab interface)

辨识所使用的数据长度保持不变，每增加一个新数据就抛掉一个老数据，使参数估计值始终只依赖于有限个新数据所提供的新消息，克服了遗忘因子法不管多老的数据都在起作用的缺点，因此该算法更能有效的克服数据饱和现象。(Identify the use of data length remain the same, every time you add a new data will throw away an old data, make the parameter estimate always depends on just co., LTD., a new data provided by the new news, overcome the forgetting factor method no matter how old data are in action shortcomings, so the algorithm can effectively overcome the more data saturation phenomenon.)

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

自行车的非线性控制理论和建模, 英文的文件， 不过很全面 值得一看(non linear modelling and test of bike)

自己编写的基于卡尔曼滤波的利用加速度传感器的计步器，测试数据是传感器放在腰部和手臂。(A kF-based pedometer using accelerator.)

lDPC编解码程序，以MATLAB为其开发环境，采用的是LLR BP译码，对LDPC码编程有帮助。(codec lDPC procedures to MATLAB for their development environment, using the LLR BP decoding of LDPC codes assist programming there is.)

一些matlabde 应用程序，20个以上，适合初学者学习和研究。(Matlabde some applications, more than 20, suitable for beginners to learn and research.)

matlabb标准粒子群优化算法。 电力系统的分析和计算中，需要不同网络结构和参数。在应 用这些参数之前，收集和整理工作会花费大量的时间和精力。(matlabb standard particle swarm optimization. Power system analysis and calculation, require different network structures and parameters. Before applying these parameters, the collection and collation will spend a lot of time and effort.)
