Solve numerically a system of two SDEs and one ODE

Hi,

The title says it all really. I need to solve numerically a system of two stochastic differential equations and one ordinary differential equation.

I am afraid I can't post any code as I don't even know where to start. I have researched and found SDE and SimByEuler functions but not sure how to apply either to my situation. I presume I need to use SimByEuler. I would like to use Euler-Maruyama method to solve the system of three equations numerically.

Can anyone maybe point me in the right direction or suggest where to look please? I am an undergraduate in maths and have looked in all the books in the library and can't find anything. I haven't been taught about SDEs so may not be able to understand much, so simple as possible would be great.

Thanks in advance
