在matlab中，使用Koetter-Vardy算法进行Reed-Solomon码的解码。(in Matlab. use Koetter- Vardy algorithm for Reed-Solomon codes decoder.)

CSR与NFC集合工具，NFC是只能适合复旦微的芯片，CSR适合ROM版本和FALSE版本(CSR and NFC collection tools, NFC is only suitable for fudan micro chips, CSR for ROM version and FALSE version)

振动理论中的主动控制程序，对于振动方面的学习有一定的帮助。(The active control of vibration theory program, the vibration aspects of learning have some help.)

说明：  基于SPWM调制的两电平三相逆变器，可实现直流电变交流电(Two-level three-phase inverter based on SPWM modulation algorithm,DC to AC.)

The program implements the use of χ2 test for determining the distribution law of fluctuations of the signals. Hypotheses about the distribution of this or innogo parameter system, such as expectation, variance, probability density for a given level of significance accepted or refuted, in accordance with the results. The program implements two distributions: the exponential and Rayleigh.

比较生存曲线可以用统计假设测试日志秩检验。它是用来测试的零假设，没有任何区别的人口的生存曲线（即概率事件发生在任何时间点是相同的每个人口）.这个函数使用卡普兰曲线的程序来估计生存函数.(Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population). This function use the Kaplan-Meier procedure to estimate the survival function, so it is mandatory to download )

主要描述了matlab中拟合与插值的方法，用插值法来应对实验数据不足的情况。(the code is mainly about the interpolation and fitting.If you don t have enough interpolation, you can use it.)
