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

Numeric or algebraic (symbolic) solution?

If you know the mathematics then it is just a matter ofwriting all the steps required to solve the equation in pseudo code, then converting that into C.

What is that supposed to mean? If you want help with your problem then a) at least show you have made some effort, and b) provide proper details, rather than terse meaningless responses.

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.
