burgers方程求解，采用fortran编写，有详细的说明，效果非常好(burgers equations, using fortran prepared a detailed description of the effect is very good)

Finit element magnet method (FEMM) software

说明：  最速下降法就是梯度下降法,可以用于求解最小二乘问题(线性和非线性都可以)。可以说是求解机器算法的最古老、最经典的模型，另一种常用的方法是最小二乘法。(The steepest descent method is the gradient descent method, which can be used to solve the least squares problem (both linear and non-linear). It can be said that it is the oldest and most classical model for solving machine algorithm. Another commonly used method is the least square method.)

牛顿 非牛顿流体数值模拟源代码，对粘弹性流体湍流减阻进行分析(Newton non-Newtonian fluid numerical simulation of the source code, to analyze the viscoelastic fluid turbulent drag reduction)

国外的地震有限元程序，美国伯克利大学的，非常经典(Earthquake abroad finite element program, the United States Berkeley, very classic)

二维交错网格SIMPLE算法fortran计算程序，包括主程序和用户定义程序。(The two-dimensional to SIMPLE algorithm the fortran calculation procedures staggered grid, including the main program and the user-defined procedures.)

In this section we introduce the idea of Galerkin approximations by considering a simple 1-d boundary value problem

根据给定的等距结点上的函数值与一阶导数值, 用埃尔米特等距插值公式计算指定插值点处的函数值。(According to the given equidistant nodes function value with a first derivative values, with equidistant interpolation Hermite interpolation formula specified function value at the point.)

在第一个图像中的每个描述符，选择它的匹配到第二个图像。(For efficiency in MATLAB, calculating dot multiplication between unit vectors is faster than Euclidean distance. Please note that: The ratio of attention to angle (the cosine of dot product of unit vector) is the approximate value of the ratio of Euclidean distance of small angle.)
