pfc matlab，建立PFC模型，并进行仿真，得到输如遇输出波形(pfc matlab)

DICOM to NIfTI converter by Xiangrui Li

这是学习matlab的一些资料，对刚入门的朋友会很有帮助(This is a matlab to learn some of the information, for beginners, friends will be helpful)

另一个ＬＥＡＣＨ算法的ＭＡＴＬＡＢ仿真源代码程序(Another LEACH algorithm MATLAB simulation program source code)

说明：  这个资料里门有很多关于matlab编程的资料，是个不错的资料(This information inside the door there are a lot of information on the matlab programming is a good information)

matlab仿真的，功能是实现相关峰值的提取。能够在低信噪比下得到效果较好的相关峰(matlab simulation, feature extraction is to achieve correlation peak. Able to get better low SNR correlation peak)

判断数据是否符合概率分布；内含多种概率分布(Determine whether the probability distribution of the data)

数字信号处理的课程设计，用matlab对给定音频信号进行处理。(Course design of digital signal processing using MATLAB to process the audio signal is given.)
