matlab的可执行程序-Matlab executable

用VB实现解常微分方程组 包括定步长四阶龙格-库塔法、自适应变步长的龙格-库塔法、改进的中点法、外推法等-VB solution of ordinary differential equations including fixed step 4-order Runge- Kutta method, adaptive variable step of the Runge- Kutta method to improve the midpoint of the law, such as extrapolation

此程序用来求取反射系数。通过左普利兹方程组，知道反射角，给出两层水平地层的横波速度，纵波速度，以及两层的密度，即可来求取反射系数，透射系数。超过临界角时候，使用虚数，并取模作为最终结果。此程序可用来进行地球物理中，反射波，投射波能量、振幅的求取。

HMM算法的C++实现. 在Linux下编译的Makefile，同时经过测试，可以在Windows下通过Visual Studio 2013编译通过。 总之，学习HMM必备的利器啊。。。。

一维伽辽金型无网格法MATLAB程序 无网格方法采用基于点的近似，可以彻底或部分地消除网格，不需要网格的初始划分和重构，不仅可以保证计算的精度，而且可以大大减小计算的难度。然而，由于目前的无网格近似一般没有解析表达式，且大都基于伽辽金原理，因此计算量很大，要超出传统的有限元法；另外，无网格近似大都是拟合，因此对于位移边界的处理比较困难，多采用拉格朗日乘子法处理。-1维伽Galerkin-type meshless method MATLAB procedures meshless method based on the point of approximation, can be completely or partially eliminate the grid, the grid does not require the initial division and reconstruction, not only can guarantee the accuracy of the calculation, and can greatly reduce the difficulty of calculation. However, due to the current meshless approximation there is no analytic expression in general, and mostly based on the Galerkin principle, the calculation of a large volume, it is necessary to go beyond the traditional finite element method In addition, the meshless approximation are fitted, so displacement of the border more difficult to deal with, the use of Lagrange law.
