代码说明：

介绍了一种可在较短时间内检测到数字电视国标系统工作模式的方法。该方法利用帧头PN序列和PN序列扩展保护部分的相关特性、循环特性以及0FDM信号部分的周期特性进行判决，可达到很好的检测效果，该方法同时可加入跟踪模块对系统工作模式的突然改变作出反应。还介绍了两种可以在硬件资源和性能上进行折中的检测方法(Describes a method can be detected in a relatively short period of time to a digital television GB system working mode. The method utilizes the correlation characteristics of the the header PN sequence and the PN sequence extension protective portion, the cycle characteristics of the cycle the characteristics and 0FDM signal portion judgment can achieve good detection results, the method at the same time tracking module may be added to the system working mode sudden change the response. Also describes two hardware resources and performance compromise detection method)

利用MATLAB程序中的inline和nlinfit两个命令对血药浓度-时间数据进行非线性拟合,求解血管外给药的药动学参数。同时与3P97软件计算结果进行了比较,结果表明,基于MATLAB程序可方便快速地求解血管外给药的各个药动学参数,计算结果与3P97软件计算值相当,且本方法操作简便、界面直观、易于推广,可用于临床教学或实验中药动学参数的计算。更多还原 (Using MATLAB program inline and nlinfit two commands to the plasma concentration- time data by nonlinear fitting, solving the pharmacokinetic parameters of extravascular administration. Simultaneously with the 3P97 software to calculate the results were compared, the results show that can quickly and easily solve extravascular administration of various pharmacokinetic parameters based on MATLAB, the results calculated with 3P97 software fairly, and that the method is simple, intuitive interface, easy to spread, can be used to calculate the clinical teaching or experimental medicine pharmacokinetic parameters.

说明：寻找三次样条多项式需要求解大量的线性方程。实际上，给定N个断点，就要寻找N-1个三次多项式，每个多项式有4个未知系数。这样，所求解的方程组包含有4*(N-1)个未知数。把每个三次多项式列成特殊形式，并且运用各种约束，通过求解N个具有N个未知系数的方程组，就能确定三次多项式。 (find cubic spline solving polynomial need a lot of linear equations. In fact, given N breakpoints, it is necessary to look for N-1 cubic polynomial, each with four polynomial coefficients unknown. Thus, by solving the equations contain 4* (N-1) unknown. Each cubic polynomial Timing special form, and use of various constraints, by solving N with N unknown coefficient equations, we can identify three polynomial.)

该程序用matlab写成，已包含vof（根据Hirt的方法）内容，但该部分尚不成熟。对于不包含自由面的计算比较成功。(The program written with matlab, included vof (according to Hirt' s method) content, but that part is not yet mature. For the calculation of the free surface does not contain more successful.)
