Solve coupled second order differential equations using ODE45

Hi,

I am trying to solve the following second order equations using ODE45 and plot them but all I am getting are straight line graphs running on the x-axis which is wrong.

Equations:

1] x''+Ax+By=0

2] y''+Bx+Cy=0

where, A,B,C are constants. All initial conditions=0.

Can anyone help me out please?

Solution is x=y=0. So it's not surprising that you get straight line graphs.

Yes, I just realised how stupid I was being. I changed the conditions and got a graph. Cheers
