[R-sig-dyn-mod] ode with variable parameters

[Thomas.Hoffmann at bafg.de]

Dear all,

I would like to solve a simple diffusion-advection equation: dC/dt = v * C + gamma dC/dx

In which v and gamma changes through time. Basically I have a dataframe, which gives v and gamma at the time-steps that I use to solve the above equation with ode.1d.

How do I solve this problem dynamically with variable parameters.


Thanks for your help
Kind regards
Thomas
