Runge-Kutta 4th-Order Java Application. It can be used to get the Butcher Table for various version of RK4. it is also useful in getting the ODE solution by using the initial conditions. It is useful in most engineering application.

5个f语言有限差分正演程序，应用有限差分法在CPML边界条件下进行2D正演，前四个程序分别对应各向异性介质、各项同性2阶精度、各项同性4阶精度、双相介质4阶精度四种不同情况。最后一个是3D粘弹性介质的程序。-5 f language finite difference modeling, application of finite difference method under CPML boundary conditions 2D forward, the first four program
