[Maxima] numerical sol'n of vector ODE

[Dan Solomon]

I have a modestly complicated ODE in 3-space, complicated enough that  
there is no closed form solution.  I would like to see a numerical  
solution through a given initial point.  That is given dx/dt = A . x  
(where x is a 3 vector) and an initial point x0, I'd like to get  
maxima to compute the trajectory through x0 and show me a 3d plot.   
Does maxima know how to do this?

thanks!
