Vector field for a system of odes
2
Assume that you have the ode system
x'=xy-y,
y'=xy-x
How would one use pst-ode.sty to draw trajectories and vectorfield, say in the t-y plane?

Dear Herbert thank you. Dear Kurt I have tried something similar to Herbert's code. My main issue is how do you deal with the vector field. If I am not mistaken the psVectorfield command takes care of an ode with one uknown function. Here we have a system with two functions x(t) and y(t). How do you deal with this? So about the vector field Kurt, I have no code I tried because I have no idea how to setup such a command.
