自己编写的求解模糊熵程序，eemd分解，并求模糊熵，简单易懂，可实现( solve the fuzzy entropy, easy to understand, can be realized)

包括4天线准正交码的编码和解码程序，其中解码程序包括部分行的合并解码(Including 4 antenna quasi-orthogonal code encoding and decoding procedures, which include decoding part decoding the combined line)

butt,cheb1,cheb2,elip四种常见的IIR滤波器使用小例子(butt, cheb1, cheb2, elip four common small example of the use of IIR filters)

一种WaterFillingAlgorithm，资料全面，解析透彻，对学习的人很有帮助！(A WaterFillingAlgorithm, information on a comprehensive, thorough analysis of the study were very helpful!)

拉格朗日算法已知三组温度与压力数据:(3,53.5) (4,55.3) (5,56.2)求4.15对应的值为55.492375，结果正确。如果将以上数组顺序颠倒，已知压力55.492375求对应的温度，结果为4.185739，可以看到上下两个结果误差较大，就是说不能象这样去颠倒顺序去求值的。但是实际上我们可能经常要求知道压力去求温度，那么遇到这样的情况，只能采用试算法：一种简单的方法就是二分法迭代，书上都有介绍就不多讲了。(Lagrange method已知三组温度与压力数据:(3,53.5) (4,55.3) (5,56.2)求4.15对应的值为55.492375，结果正确。如果将以上数组顺序颠倒，已知压力55.492375求对应的温度，结果为4.185739，可以看到上下两个结果误差较大，就是说不能象这样去颠倒顺序去求值的。但是实际上我们可能经常要求知道压力去求温度，那么遇到这样的情况，只能采用试算法：一种简单的方法就是二分法迭代，书上都有介绍就不多讲了。)

rand 主要用于matlab中编程。主要是介绍rand的一些基本用法 大家有不懂得可以上网查(rand is for newer)

关于柴油机与液力变矩器匹配的一些论文，很好的知识(Many designs of rotary engine were proposed in the past 100 years, including the recent rotary vane concept 10 , but only the gasoline Wankel engine has become a production success. This has good power-weight ratio, inherent balance, and smoothness, but suffers from reduced effi ciency, sealing, and emissions prob-lems, particularly of unburned hydrocarbons 1)

岩石物理建模的程序，在弹性参数与物性参数关机，以及横波速度估算等领域可以应用(Rock physics modeling procedures, shut down in the elastic parameters and material parameters, and the shear wave velocity estimation can be applied to the field )
