Thanks John, I will try that! My program is based the dynamic response of a system in the time domain. It was for an assignment last year, but I never quite got it to work so I thought I would try again. My prof told us ODE 45 would not work, he didn't say why though.

I have 15 equations with 15 unknowns describing a dynamic process. I would like to know how I can conbine solving non-linear equations together with ordinary differential equations (1st and 2nd order) simultaneously, without using ode45, but Euler's method.
