说明：  逆BROYDEN迭代法求解非线性方程组：是一种相对比较新的一种方法,克服了牛顿迭代法需要求导数和求逆的缺点。本程序提供解法和画图流程，注意多迭代几步(Inverse BROYDEN iteration method is a relatively new method for solving nonlinear equations, which overcomes the shortcomings of Newton iteration method in derivative and inversion. This program provides solution and drawing process. Remember more several steps of iteration.)

正入射的自由曲面透镜设计，计算获得透镜的二维坐标(The free-form surface lens is incident on the design, the two-dimensional coordinates of the lens calculated)

这些代码可以用于产生一系列随机数，可以根据需要使用。(These codes can be used to generate a series of random numbers may be used as needed.)

关于流体计算软件FLUENT中Y+设置的一些建设性的讨论，值得大家参考。(On computational fluid dynamics software FLUENT some constructive discussions in the Y+ set is worth your consideration.)

对于空间上的任意几个点所在的直线或曲线，该程序可以拟合出的方程。(For any of several points on the space where the line or curve, the program can fit out of the equation.)

蒙特卡罗方法用于随机过程的处理，其重要应用软件如geant4，本书详细介绍了蒙卡的理论和应用，有很好的参考价值(Monte Carlo method is used for treatment of stochastic processes, and its important applications such as geant4, the book details the theory and application of Monte Carlo, have a good reference value)

反密法在数值计算中的地位就不用我来一一列举了，此程序就可以轻易的使其实现。(anti-secret numerical calculation method in the position I would not have to list them one by one, this procedure can easily achieve it.)

谐波检测的RELAX算法，优于FFT,能够对幅值，频率，相位进行有效估计(an algorithm for estimation of sinusoid parameter)

最小二乘法的证明及matlab程序，附有文字说明和程序源码(The method of least squares)

利用下载的goce原始数据，计算得出含有时间/经纬度/重力梯度格式的程序(Use downloaded goce raw data, calculated with the time/latitude/gravity gradient program formats)
