如何在C中求解微分方程 [英] How Do I Solve A Differential Equation In C

问题描述

我一直在尝试用C编写代码来解决大气辐射的比尔 - 兰伯特定律。我需要一个小的微分方程的C代码（供我参考），具有下限和上限以及积分



先谢谢

I have been trying to write a code in C to solve Beer-Lambert law for Atmospheric Radiation . I need C code for a small differential equation (for my reference) with lower and upper limits and integration

Thanks in Advance

推荐答案

您必须先学习Numerical Analyis。不是整个事情，只是差分方程部分。您可以进一步缩小范围，因为解决ODE和PDE的方法不同。



我之前使用的是Euler和Runge Kutta方法（用于ODE）。这些是数字技术。除非你说出什么样的等式，它的程度和顺序，否则不可能提出任何建议。

You must study Numerical Analyis first. Not the entire thing, just the differential equaions part. You can narrow it down further because solving ODE and PDE have different approaches.

I have previously used Euler and Runge Kutta methods (for ODE). These are numerical techniques. It's impossible to suggest anything unless you say what kind of equation, it's degree and order.
