一个应用程式求解XPP微分方程,延迟方程,函式方程、边界值问题,随机方程。 它是基于流行的程式XPPAUT和使用相同的颂诗档案语法。接口已经完全重写为iPhone。 XPP将nullclines、方向领域,和两个——和三维块解决方案以及找到平衡分,其稳定性和separatrices。 用户可以选择一打不同的数值集成商。 计算数据可以导出通过iTunes。 使用滑块,可以观察系统的行为变化为参数有所不同。 解决你所有的微分方程问题与XPP。 添加任何成千上万的方程来图书馆直接从WWW或进口通过iTunes。 XPP is an app for solving differential equations, delay equations, functional equations, boundary value problems, and stochastic equations. It is based on the popular program XPPAUT and uses the same ODE file syntax. The interface has been completely rewritten for the iPhone. XPP will draw nullclines, direction fields, and two- and three-dimensional plots of solutions as well as find equilibrium points, their stability and separatrices. Users can choose from a dozen different numerical integrators. Computed data can be exported via iTunes. Using the sliders, it is possible to watch how the behavior of the system changes as parameters vary. Solve all your differential equations problems with XPP. Add any of thousands of equations to your library directly from the WWW or import via iTunes.
