Passing parameters to the RHS of an ODE

[Eduardo Gallestey Alvarez]

Hi,

I am a newcomer to Octave. My problem is as follows:

I want to solve an ODE, where the RHS of the differential equation
should receive some parameters 

(i.e. dot(x)= f(x,t,P1,P2,...) ). 

Is there a way to do that? I tried to find it in the manual and in the
archive of "old questions" but I couldn't find anything useful!

Thanks,
Eduardo
