Applying Boundary Condition to ODE45
显示 更早的评论
Hi all,
I have a set of coupled differential equations which are readily arranged to be solved on ode45 in a domain [0 L]. However, all the boundary conditions of the differential equations are given at x=L instead of x=0. I cannot enforce these BCs to my problem using MATLAB. How can i accomplish that ? (I would like to solve set of ODEs using 4th order Runge Katta Method)
Kind Regards

Hi,
you can reverse tspan. If you for example use:
tspan = [20 0]
then the integration will be backwards and your condition is an initial condition.
Best regards
Stephan
