主要功能是turbo码的viterbi译码的matlab仿真(Main function is to viterbi decoding turbo codes matlab simulation)

产生一个满足泊松分布的随机序列信号。用于通信系统的信源部分(have to meet a Poisson distribution of random sequence. Communication systems for the source of)

先对陀螺仪测量数据进行预处理，每隔100行抽取一行数据，以第7列数据为例，用ALLAN方差法分析出五项主要参数(First gyroscope measurement data preprocessing, extract a row of data every 100 rows, seven of data, for example, ALLAN variance analysis of the five main parameters)

face recognition with R and C matrix. get a picture from a defined path and construct the R and C matrix and find the points that are related to the face part of the given picture

matlab编写克里金差值的说明技术文档，包含具体的算法(The kriging software described in this document was developed by Dezhang Chu with funding the National Science Foundation through the U.S. GLOBEC Georges Bank Project s Program Service and Data Management Office. It was originally inspired by a MATLAB toolbox developed by Yves Gratton and Caroline Lafleur (INRS-Océanologie, Rimouski, Qc, Canada), and Jeff Runge (Institut Maurice-Lamontagne, now with University of New Hampshire).

用于计算互近似熵，互近似熵是两个信号之间不同步的量度。模糊熵与互信息(It is used to calculate the mutual approximate entropy, and the mutual approximate entropy is a measure of the non synchronization between the two signals)

g(x)=f(m,n,L), 其中,m,n,L均服从正态分布,分布情况也在所给的图中. 使用matlab,用蒙特卡罗模拟法 对该函数进行模拟,得出g(x)大于0的概率.(G (x) =f (m, N, L), of which, m, N, L are the normal distribution, distribution is also in the picture. The use of MATLAB, simulates the function by Monte Carlo method, the G (x) greater than 0 probability.)
